Abstract:

ABSTRACTThe fat plus protein yield of 70 011 records of pedigree British Friesian/Holstein cows was regressed on various components of their dam's Cow Genetic Index (CGI) in order to obtain the regression coefficients for comparison with the index weights currently used in the calculation of the CGI. For the first and later (2 to 5) lactation components of the CGI, the regression coefficients obtained by analysis were consistent with the tabulated index weights, but the coefficients for the sire component tended in some cases to be lower than the table values. The analysis was repeated using only dams that had widely used sires. The partial regression coefficients for the first and later lactation components were again consistent with the tabulated weights, and the coefficient for the sire component lay within one s.d. of the table values. In all cases, a cow's CGI is shown to take full account of her first and later lactation information and her sire's and dam's transmitting abilities.

AbstractObjectiveThe study evaluated the association between consumption frequencies of the major food categories and the risk of new depression four years later in older Taiwanese.DesignA prospective cohort study with multistage random sampling. Logistic regression analysis evaluated the significance of the longitudinal associations of intake frequencies of the major food categories with future (4 years later) risk of new depression, controlled for possible confounding factors with or without adjustment for cognitive status.SettingPopulation-based free-living elderly.SubjectsMen and women (n 1609) ≥65 years of age.ResultsIn a regression model that controlled for demographic, socio-economic, lifestyle and disease/health-related variables but not cognitive status, both fruits (OR = 0·66, 95 % CI 0·45, 0·98, P = 0·038) and vegetables (OR = 0·38, 95 % CI 0·17, 0·86, P = 0·021) were protective against depressive symptoms 4 years later. However, when the same regression model was also adjusted for cognitive status, only vegetables (OR = 0·40, 95 % CI 0·17, 0·95, P = 0·039) were protective against depressive symptoms. Higher consumption of eggs was close to being significant in both regression models (P = 0·087 and 0·069, respectively). Other food categories including meat/poultry, fish, seafood, dairy, legumes, grains and tea showed no significant associations.ConclusionsResults suggest that although confounding factors cannot be totally ruled out, more frequent consumption of vegetables seems to be protective against depressive symptoms in the elderly. Further studies are needed to elucidate the causal role and the mechanism of the association.

Abstract:

The purpose of this study was to determine whether bullying perpetration in early adolescence is capable of predicting delinquency 1 year later. Nine control variables were included in a regression analysis of the bullying–delinquency relationship in 1,001 schoolchildren ([Formula: see text] age = 12.97 years). The nine control variables (age, sex, race, social support, bullying victimization, probullying attitudes, parental knowledge, impulsivity, and peer delinquency), along with bullying perpetration and prior delinquency, were regressed onto delinquency measured 1 year later. Because the majority of participants (63.3%) were missing data on the outcome measure, a full information maximum likelihood (FIML) with auxiliary variables was performed. The results of a preliminary confirmatory factor analysis demonstrated that the bullying and delinquency scales employed in this study were assessing separate constructs. The main analysis revealed that parental knowledge, impulsivity, bullying, and precursor delinquency predicted delinquency one year later.

Abstract:

BackgroundSeveral studies show that youth unemployment is associated with worse mental health later in life. However, existing studies report results for only one model, or a few models, and use regression adjustment to support causal claims. We use two novel methods to address these gaps in the literature.MethodsWe use data from Next Steps, a cohort study of English schoolchildren who entered the labour market in the aftermath of the 2008–2009 global financial crisis, and measure mental health using the 12-item General Health Questionnaire (GHQ-12) at age 25. We use specification curve analysis and a negative control outcome design (a form of placebo test) to test whether associations between youth unemployment and later GHQ-12 scores are sensitive to model specification or are likely to be confounded by unobserved factors.ResultsWe find that the association between unemployment and later GHQ-12 is qualitatively similar across 99.96% of the 120 000 models we run. Statistically significant associations with two placebo outcomes, height and patience, are not present when regression adjustments are made.ConclusionsThere is clear evidence that youth unemployment is related to later mental health, and some evidence that this cannot be easily explained by unobserved confounding.

Abstract:

To study risks for abuse and later homicidal behavior, 192 abused infants ( M age = 3.12 yr., SD = 1.48; 82 girls, 110 boys) and 192 controls were matched on demographics and examined; data discriminating abused and later homicidal cases were analyzed with Shao's bootstrapped logistic regression. Predictors of Abused status were injury, burn, poisoning, fetal substance exposure ( OR = 2.47), later parental or youth court contacts ( OR = 1.86e+12), and parental alcohol abuse (OR = .54; AUC = .99; 95% CI= .96−.99). Youth tracked through records 12 years (to M age = 12.17 yr., SD =1.89) were classified into Abused Later Homicidal (11%, n = 21), Abused Later Violent (14%, n = 27), Abused Later Delinquent (31%, n = 60), Abused Later Nondeliquent ( n = 44), and Control groups ( n = 192). Data were analyzed similarly. When the Abused Later Homicidal was contrasted with the Control group, predictors of homicide were three or more home/school moves ( OR = .78), illnesses ( OR = .90), and later court contacts ( OR= 1.75e+07; AUC=.99; 95% CI=.90−.98). When the Abused Later Homicidal was compared with the Abused Later Nondelinquent group, predictors of homicide were poorer executive function ( OR = 2.29) and later court contacts ( OR = 7.78e+06; AUC=.94; 95% CI= .90−.98).

Abstract:

Ratio type regression estimator is a prevalent and readily implemented heuristic under simple random sampling (SRS) and two-stage sampling for the estimation of population. But this existing method is based on the ordinary least square (OLS) regression coefficient which is not an effective approach in the presence outliers in the data. In this article, we proposed a class of estimators firstly for complete auxiliary information and, later on, for partial auxiliary information for the presence of outliers in the data. To address this problem, initially we presented a distinct class of estimators by introducing the characteristics of L-moments in the existing estimators. Later on, quantile regression estimators are defined as more robust in the presence of outliers. These techniques empowered the proposed estimators to handle the problem of outliers. To prove the better performance of the proposed estimators, numerical studies are carried out using R language. To calculate the mean square error (MSE), hypothetical equations are expressed for adapted and proposed estimators. Percentage Relative Efficiencies (PRE) are compared to justify the proposed estimators.

Abstract:

A series of multiple regression analyses using the most recent publicly available data on the salaries of veteran hitters in major league baseball uncovers little evidence of economic discrimination by race. Comparisons of unstandardized regression coefficients for player variables, by race and position, reveal a number of instances of inequality. However, these inequalities do not occur consistently with respect to the same type of performance, nor do they always place blacks at a disadvantage. Furthermore, blacks who do not enjoy the market power granted to players by the advent of free agency are not uniformly victimized by discrimination in salaries. Instead, the newest evidence suggests that signs of salary discrimination that were found in data on hitters from the 1977 season are not manifest 10 years later.

Abstract:

To study risks of abuse, violence, and homicide, 181 Abused Children ( M age= 12.85 yr., SD = 2.14; 58 girls, 123 boys) were matched with 181 clinic-referred Controls. Data analysis was Shao's bootstrapped logistic regression with area under curve ( AUC) and odds ratios ( OR). Predictors of abused status were court contacts ( OR = 2.04e+22) and poorer executive function ( OR = .81; AUC=.99; 95% CI = .91−.99). Groups were tracked forward in records for 9 years ( M=8.78 yr., SD =1.41). Looking forward, youth ( M age = 21.63 yr., SD = 2.07) were classified into Abused Children Later Homicidal (5%, n = 10), Abused Children Later Violent (23%, n = 41), Abused Children Later Delinquent (28%, n = 50), Abused Children Later Nondeliquent (44%, n = 80), and Controls ( n = 181). Data were analyzed with two more logistic regressions. Predictors of Abused Children Later Homicidal compared with Controls were number of court contacts ( OR =50,398.78) and poorer executive function ( OR = 79.72; AUC =.91; 95% CI= .80−.95). The predictor of Abused Children Later Homicidal contrasted with Abused Children Later Nondelinquent was court contacts ( OR = 2,077,089,352; AUC=.87; 95% CI =.65−.95). The common predictor for Abused Children and Abused Children Later Homicidal groups was court contacts.

Abstract:

Abstract Despite consistent evidence on the negative effect of precarious employment on health, little is known about the dynamic pattern of employment over the life course on later year health. Using the longitudinal data (1-18 waves) from the Korean Labor & Income Panel Study (KLIPS) (n=1,705), this study aimed to (1) identify long term change patterns of employment in two middle-age groups (early middle-aged: 40-49 / late middle-aged: 50-59), (2) examine the association between the patterns and self-rated health in old age. We apply sequence analysis with 18 years of working status and conducted regression health outcomes in the 18th wave. The result of sequence analysis found the differential employment patterns: among the early middle-aged, five patterns were identified consistently full-time, consistently not- working, transit to self-employed, mixed pattern, retired. Among the late middle-aged, five patterns were identified: consistently full time, mixed pattern, consistently retired, transit to not- working, consistently not working. Regression results indicated a negative association between precarious employment history and health in later years: Among the early middle-aged, members in the “consistently full-time” were likely to have better health compared to “transit to self-employed”. Among the later middle-aged, “retired” and “transit to not –working” were likely to have better health compared to “mixed pattern group”. The findings suggest the importance of employment history in middle age to predict the health outcome in later life. Policies to support experiencing precarious or self-employment are needed to prevent health disparity in later life.

Full text

Abstract:

Mean calving dates among 7 wild reindeer (Rangifer t. tarandus) herds in southern Norway varied between the 6th and the 27th of May. Ln transformed foetus weights relate linearly to ln age in days. Regression analyzes based upon 225 days pregnancy predicts birth wet weights between 4600 and 7500 g in the different areas and years. At 130 days, foetus weights varied between 547 and 746 g (mean=681, standard deviation s=63) in all areas and years, indicating that foetus growth up to this size is independent of mothers body weight or condition. During the remaining 95 days of pregnancy, very poor body condition, reflected in dressed weights, resulted in slower foetus growth and smaller regression estimated birth weights. The foetus weight variation recorded at similar dates within areas and sampling years indicates a dispersed breeding time mostly within two ovulations. A small sample of foetuses from pregnant yearlings and calves indicate that these cohorts conceive later than 2 yr + females. Assuming similar foetus growth pattern among all female age cohorts within areas, yearlings conceive around 1 week later and calves (in Ottadalen) more than 3 weeks later than 2 + yr olds.

Abstract We present a new and simpler regression model for the estimation of the first oxidation potentials (Ep1) of flavonoids based on the number of phenolic, alcoholic, and carboxylic OH groups. In the regression we included the Ep1 of 12 polyphenols (mostly flavonols and catechins) that were measured in our laboratory at pH 3. The model yielded r=0.986 and SE=0.040. Later successive inclusions of previously reported Ep values into the regression model, 7 at pH 3, the model (N=19) yielded r=0.980, SE=0.046 and 19 at pH 7 the model (N=38), yielded r=0.985, SE=0.044.

N (0,σ2) random errors with variance σ2>0 but later it was found that there was a change in the system at some point of time m and it is reflected in the sequence after Xm by change in slope, regression parameter β2. The problem of study is when and where this change has started occurring. This is called change point inference problem. The estimators of m, β1,β2 are derived under asymmetric loss functions, namely, Linex loss & General Entropy loss functions. The effects of correct and wrong prior information on the Bayes estimates are studied.

Abstract:

AbstractThis study tested the prospective association between observational indicators of temperament, which were obtained across multiple assessments when children were 6–36 months of age, and parent and teacher reports of children's attention-deficit/hyperactivity disorder (ADHD) behaviors, when children were in first grade. Data were drawn from the Family Life Project and included 1,074 children for whom temperament and either parent- or teacher-reported ADHD behavioral data were available. The results of variable-centered regression models indicated that individual differences in temperament regulation, but not temperamental reactivity, was uniquely predictive of parent- and teacher-reported ADHD behaviors. Latent profile analyses were used to characterize configurations of temperamental reactivity and regulation. Person-centered regression models were subsequently estimated in which temperamental profile membership replaced continuous indicators of temperamental reactivity and regulation as predictors. The results of person-centered regression models indicated that temperamental reactivity and regulation both contributed (both alone and in combination) to the prediction of subsequent ADHD behaviors. In general, the predictive associations from early temperament to later ADHD were of modest magnitude (R2 = .10–.17). Results are discussed with respect to interest in the early identification of children who are at elevated risk for later ADHD.

Abstract:

AbstractSocio-economic circumstances influence later-life employment participation, which may take different forms as retirement processes are complex. We aimed to explore the diverse effects of various socio-economic sub-domains on pre- and post-retirement employment. We used Finnish register data to examine socio-economic predictors of time to retirement (i.e. receiving the statutory pension) using Cox regression analysis and on time spent in post-retirement employment using repeated negative binomial regression analysis over a follow-up between the ages of 63 and 68, i.e. the flexible pension age range. An average wage earner still employed at age 62 spent 13.5 months in pre-retirement employment (this corresponds to time to retirement) and 4.8 months in post-retirement employment. Those with tertiary education retired later, but the educational differences in the total time spent in employment were small when post-retirement employment was also considered. There was little variation in the timing of retirement by household income, but those in the highest quintile spent the longest time in post-retirement employment. Upper non-manual employees, home renters and those with high household debt retired later, and those with high household debt also spent a longer time in post-retirement employment. In a national flexible pension age system, high occupational class and household income thus appear to encourage either later retirement or participation in post-retirement employment. However, economic constraints also appear to necessitate continued employment.

Abstract:

Objective: Timing and accumulation of work-related exposures may influence later life health. This study evaluates the association between women’s work patterns and physical functioning. Method: Work history and physical functioning information was collected at baseline for U.S. women ages 50 to 79 years in the Women’s Health Initiative Observational Study ( N = 75,507). We estimated life course workforce participation patterns using latent class analysis. Associations between work patterns and physical limitations were explored using modified Poisson regression. Results: Compared with working continuously, women who left the workforce early had 8% increased risk and women who worked intermittently had 5% reduced risk of physical limitations later in life. The negative association with intermittent workforce participation was stronger for women with substantively complex work (9% reduced risk) than for women with nonsubstantively complex work (2% reduced risk). Discussion: Life course work patterns and characteristics may contribute to physical functioning later in life among women.

Abstract:

AbstractThe aim of the present study was to analyze the relative influence of age at implantation, parental expansions, and child language internal factors on grammatical progress in children with cochlear implants (CI). Data analyses used two longitudinal corpora of spontaneous speech samples, one with twenty-two and one with twenty-six children, implanted between 0;6 and 3;10. Analyses were performed on the combined and separate samples. Regression analyses indicate that early child MLU is the strongest predictor of child MLU two and two-and-a-half years later, followed by parental expansions and age at implantation. Associations between earliest MLU gains and MLU two years later point to stability of individual differences. Early type and token frequencies of determiners predict MLU two years later more strongly than early frequency of lexical words. We conclude that features of CI children's very early language have considerable predictive value for later language outcomes.

Abstract:

The purpose of this research was to investigate full-day kindergarten, as a means of improving later academic achievement. A total of 208 students who had continuous enrollment for three consecutive school years from a school district in southern California participated in the study. The sample contained 165 students who had attended the traditional half-day kindergarten program with 43 attending a hybrid all-day kindergarten program. All students were administered the California Standardized Testing and Reporting (STAR) assessment and the California Achievement Test 6th Edition (CAT 6) survey exams. Using stepwise multiple regression, several independent variables were introduced into the regression equation to obtain a Prediction Model of Student Success. The English language arts and math scores of the California STAR Assessment were used as the dependent variable separately. A significant model was not developed. Using an independent-sample T Test procedure, comparing the two groups, was also preformed revealing that there were no significant differences in students who attended the all-day kindergarten program and students who attended a traditional kindergarten program.

Abstract:

Seed yields and oil contents were determined for several sunflower cultivars grown in the south-east of South Australia over a range of environments which included different locations and years. Data were analysed by modified joint regression techniques. Each cultivar was included in at least four experiments to allow analysis by modified joint regression. The highest seed yields were produced by Hysun 3 1, Sungold, Suncross 52, Sunking and Hysun 30, which produced 16.4, 15.4, 14.7, 12.4 and 7.4% more seed, respectively, than Peredovik. Seeds with the highest oil contents were produced by Suncross 52 (48.6% w/w) and Hysun 31 (48.3%); Hysun 10 and Stepniak produced seeds with the lowest oil content (43.7 %) . Later flowering cultivars had significantly higher seed yields and oil contents than earlier flowering cultivars, indicating that they were better adapted to the environment. For every day that flowering of a cultivar was later than that of Perodovik, mean seed yield increased by 56.6 kg/ha and oil content by 0.4%.

Abstract:

Spontaneous regression of Hodgkin lymphoma (HL) is a rare event. We describe a 32-year-old woman with spontaneous regression of HL and review the literature. The patient presented with cervical lymphadenopathy and was diagnosed with stage IIA classical HL. The patient refused to receive any treatment for her disease. Positron emission tomography/computed tomography carried out 2 years later showed complete regression of the lymphadenopathy, without pathological uptake of fluorodeoxyglucose. At the last follow-up, 3.5 years after the initial presentation, the patient is with no evidence of disease. During workup for the HL, concomitant papillary thyroid carcinoma was diagnosed, for which the patient refused treatment as well. The thyroid malignancy has remained stable throughout the follow-up.

Full text

Abstract:

Partial least squares (PLS) is a powerful tool for multivariate linear regression. But what if the data show a non-linear structure? Near infrared spectra from a pharmaceutical process were used as a case study. An ANOVA test revealed that the data are well described by a 2nd order polynomial. This work investigates the application of regression techniques that account for slightly non-linear data. The regression techniques investigated are: linearising data by applying transformations, local PLS, i.e. splitting of data, and quadratic PLS. These models were compared with ordinary PLS and principal component regression (PCR). The predictive ability of the models was tested on an independent data set acquired a year later. Using the knowledge of non-linear pattern and important spectral regions, simpler models with better predictive ability can be obtained.

Abstract:

Objective: To validate the Meaning in Life Questionnaire (MLQ) in earlier and later older-adulthood, and examine its correlates. Method: Participants in earlier ( n = 341, M age = 68.5) and later older-adulthood ( n = 341, M age = 78.6) completed the MLQ and other measures. Confirmatory multigroup analysis, correlations, and regression models were conducted. Results: A two-factor (presence and search), eight-item model of the MLQ had a good fit and was age-invariant. Presence and search for meaning were largely unrelated. Meaning was associated with life satisfaction, well-being across a range of domains, and psychological resources. Searching for meaning correlated negatively with these variables, but to a lesser degree in later older-adulthood. Discussion: The MLQ is valid in older-adulthood. Meaning in life is psychologically adaptive in older-adulthood. Searching for meaning appears less important, especially in later older-adulthood. Findings are discussed in the context of aging and psychosocial development.

Abstract:

Mean fibre diameter measurements from yearling to 5-year-old Australian fine- and medium-wool Merino sheep were analysed using several multivariate models that varied in covariance structure. A pre-structured multivariate model was found to be the most parsimonious model in comparison with the other models fitted such as banded, autoregressive and random regression. In the preferred model, the ages of mean fibre diameter for fine-wool data were genetically partitioned into yearling, 2 years, 3 years and later ages and for medium-wool data into hogget, 2 years and later ages. The estimates of genetic correlations between mean fibre diameter measured at different ages for medium-wool sheep were higher (0.89–1.00) than those for fine-wool Merino (0.75–1.00).

Abstract:

Childhood obesity is associated with alterations in hypothalamus–pituitary–adrenal (HPA) axis activity. However, it is unknown whether these alterations are a cause or a consequence of obesity. This study aimed to explore the temporal relationship between cortisol production and metabolism, and body mass index (BMI). This prospective follow-up study included 218 children (of whom 50% were male), born between 1995 and 1996, who were assessed at the ages of 9, 12 and 17 years. Morning urine samples were collected for assessment of cortisol metabolites by gas chromatography-tandem mass spectrometry, enabling the calculation of cortisol metabolite excretion rate and cortisol metabolic pathways. A cross-lagged regression model was used to determine whether BMI at various ages during childhood predicted later cortisol production and metabolism parameters, or vice versa. The cross-lagged regression coefficients showed that BMI positively predicted cortisol metabolite excretion (p = 0.03), and not vice versa (p = 0.33). In addition, BMI predicted the later balance of 11β-hydroxysteroid dehydrogenase (HSD) activities (p = 0.07), and not vice versa (p = 0.55). Finally, cytochrome P450 3A4 activity positively predicted later BMI (p = 0.01). Our study suggests that changes in BMI across the normal range predict alterations in HPA axis activity. Therefore, the alterations in HPA axis activity as observed in earlier studies among children with obesity may be a consequence rather than a cause of increased BMI.

Abstract:

Those skeptical of ecological regression in voting behavior studies continue to suggest that problems in applying the technique severely limit its utility. But the cautionary offered in the Winter 1985 number of this journal by William H. Flanigan and Nancy H. Zingale (“Alchemist’s Gold: Inferring Individual Relationships from Aggregate Data,” Social Science History 9: 71-91) goes so far as to suggest that these problems are insurmountable—or virtually insurmountable. As a user, I was prepared to be devastated, but in fact find myself cheered (if a little puzzled).Interested readers will recall that the centerpiece of the authors’ argument is a test involving this question: How did the voters of 1968 behave four years later in the presidential election of 1972? The test consists of comparing voters’ actual behavior, as determined by survey data, with ecological regression estimates of that same behavior. The tabulated results are alleged to be decisive in proving the authors’ point, but instead appear to prove just the opposite of what is intended, as a fresh look at the material reveals.

Abstract:

ABSTRACTThis paper examines the economic well-being of women who become divorced or separated in mid- or later life, using 1994 data from Statistics Canada's Survey of Labour and Income Dynamics. Economic well-being is measured by adjusted economic family total money income, before-tax low-income cut-offs, and ownership of dwelling. Women and men aged 65 and over still in their first marriages are compared with women and men, aged 65 and over, who were divorced or separated at age 45 or older. Results show that women who become divorced or separated in mid- or later life are more likely to have low income than married persons and men who become divorced or separated in mid- or later life. Persons who divorce or separate in mid- or later life are less likely than married persons to live in a dwelling that is owned by a member of the household. Regression analyses show that receiving pension income and receiving earnings are positively associated with income for women who become divorced or separated in mid- or later life. Implications for the Canadian legal and retirement income systems are discussed.

Abstract:

The aim of this study was to examine the later-life preparation pattern of Korean baby boomers and its effect on depression. Using the fourth wave of Korean Retirement and Income Study, later-life preparation was measured by economic, physical, and psychological preparation, and leisure, and family relationship satisfaction. The data analysis included latent class analysis, correlations, multiple logistic regression, and analysis of variance. Later-life patterns of Korean baby boomers were classified as high-level (35.7%), low-level (31.1%), and health and family relationship (33.2%) preparation patterns. For depression, the low-level pattern was associated with significantly higher level of depression; however, no differences were found in other two patterns. Researchers recommended a postretirement program to reflect the unique characteristics of Korean baby boomers. Moreover, findings regarding the importance of health and family relationships can be applied to other countries that have historical and cultural backgrounds similar to Korea.

Abstract:

Despite federal and state laws and regulations that require states and local districts to provide English language learners (ELLs) with support services, prior research has indicated that ELLs are, in general, lagging behind non-ELLs in academic achievement. An unanswered question is whether the initial designation of students as ELL influences their later academic achievement and how. Using a regression discontinuity design, this study compares the outcomes for students near the cutoff for being initially classified as ELL and initially fluent English proficient (IFEP) students. Among students near the cutoff, the classification had significant positive effects on ELLs’ academic achievement in elementary grades and, to some extent, in the later grades.

Abstract:

ObjectivesAn association between youth unemployment and poorer mental health later in life has been found in several countries. Little is known about whether this association is consistent across individuals or differs in strength. We adopt a quantile regression approach to explore heterogeneity in the association between youth unemployment and later mental health along the mental health distribution.DesignProspective longitudinal cohort of secondary schoolchildren in England followed from age 13/14 in 2004 to age 25 in 2015.SettingEngland, UK.Participants7707 participants interviewed at age 25.Primary and secondary outcome measures12-Item General Health Questionnaire (GHQ) Likert score, a measure of minor psychiatric morbidity.ResultsYouth unemployment was related to worse mental health at age 25. The association was several times stronger at deciles of GHQ representing the poorest levels of mental health. This association was only partly attenuated when adjusting for confounding variables and for current employment status. In fully adjusted models not including current employment status, marginal effects at the 50th percentile were 0.73 (95% CI −0.05 to 1.54, b=0.11) points, while marginal effects at the 90th percentile were 3.76 (95% CI 1.82 to 5.83; b=0.58) points. The results were robust to different combinations of control variables.ConclusionsThere is heterogeneity in the longitudinal association between youth unemployment and mental health, with associations more pronounced at higher levels of psychological ill health. Youth unemployment may signal clinically relevant future psychological problems among some individuals.

Prediction for canceled booking hotels is an important part of hotel revenue management systems in the modern era. Because the predicted result can be used for the optimization of hotel performance. The application of machine learning will be very helpful for predicting canceled booking hotels because machine learning can process complex data. In this research, the proposed methods are Artificial Neural Network (ANN) and Logistic Regression. Later it will be done five times experiments with hyperparameter tuning to see which method is the most optimal to do prediction canceled booking hotel. From five times experiments, experiments number five (logistic regression with GridSearchCV) is the most optimal for predicting canceled booking hotels, with 79.77% accuracy, 85.86% precision, and 55.07% recall.

Abstract:

In this article, we introduce two commands, rdpow and rdsampsi, that conduct power calculations and survey sample selection when using local polynomial estimation and inference methods in regression-discontinuity designs. rdpow conducts power calculations using modern robust bias-corrected local polynomial inference procedures and allows for new hypothetical sample sizes and bandwidth selections, among other features. rdsampsi uses power calculations to compute the minimum sample size required to achieve a desired level of power, given estimated or user-supplied bandwidths, biases, and variances. Together, these commands are useful when devising new experiments or surveys in regression-discontinuity designs, which will later be analyzed using modern local polynomial techniques for estimation, inference, and falsification. Because our commands use the communitycontributed (and R) package rdrobust for the underlying bandwidths, biases, and variances estimation, all the options currently available in rdrobust can also be used for power calculations and sample-size selection, including preintervention covariate adjustment, clustered sampling, and many bandwidth selectors. Finally, we also provide companion R functions with the same syntax and capabilities.

Abstract:

The purpose of this study was to examine the relation of maternal interaction styles to the development of a sample of 56 toddlers (19 low risk, 37 high risk) seen at 12 and 24 months of age. At 12 months, videotapes of mother–child interaction were coded for directiveness, sensitivity, and elaborativeness. At 12 and 24 months, cognitive and language measures were collected. A directive maternal style was negatively correlated with sensitivity and elaborativeness, whereas sensitive and elaborative ratings were positively correlated, suggesting a facilitative style. Regression models significantly predicted receptive language and cognitive development at 24 months but not expressive language. Maternal directiveness at 12 months was negatively related to later receptive language skills, whereas elaborativeness at 12 months was positively predictive of later cognitive development. Child status variables and maternal interactional styles contributed about equally to the prediction of later cognitive and language outcomes.

Abstract:

Significant associations between childhood victimization and later revictimization have materialized in previous literature; yet, the victimization cycle has been primarily explored with indicators of sexual assault, although insight into linkages between other forms of victimization remains limited. This study examined connections from family conflict exposure and physical abuse in childhood to violent crime victimization in adulthood, assessing also gender differences and neighborhood influences. Results from logistic regression and hierarchical linear modeling with data from the Chicago Longitudinal Study, a panel of 1,539 low-income, ethnic/racial minority children, unearthed a significant relation between family conflict exposure and later revictimization. Moderated by gender, these analyses showed girls exposed to frequent family conflict are particularly vulnerable to revictimization in adulthood. Exploratory analyses unveiled a potential linkage between childhood physical abuse and later revictimization for men. Neighborhood effects marginally influenced results in one instance. Public health implications are discussed.

Abstract:

Abstract This study investigates the effects of childhood misfortune and adult physical activity on later-life body mass index (BMI) and waist circumference. We use ordinary least squares regression to examine the impact of childhood misfortune (30 indicators), and adult physical activity (frequency and intensity) on waist circumference and BMI (kg/m²) using data from the Health and Retirement Study (N=5,732). Results emphasize that experiencing childhood misfortune is associated with a larger waist circumference and BMI in later life, while adjusting for social status and lifestyle variables. Adjusting for adult physical activity decreases the effect of childhood misfortune on waist circumference, suggesting mediation. The analysis reveals that the effects of childhood misfortune on BMI and abdominal adiposity are remediable. Although childhood misfortune is associated with larger waist circumference and BMI in later life, regular physical activity reduces the risk on both indicators of obesity.

Abstract:

BackgroundMedical patients are often screened for distress in the clinic using a questionnaire such as the Hospital Anxiety and Depression Scale (HADS) while awaiting their consultation. However, might the context of the clinic artificially inflate the distress score? To address this question we aimed to determine whether those who scored high on the HADS in the clinic remained high scorers when reassessed later at home.MethodWe analysed data collected by a distress and depression screening service for cancer out-patients. All patients had completed the HADS in the clinic (on computer or on paper) prior to their consultation. For a period, patients with a high score (total of ⩾15) also completed the HADS again at home (over the telephone) 1 week later. We used these data to determine what proportion remained high scorers and the mean change in their scores. We estimated the effect of ‘regression to the mean’ on the observed change.ResultsOf the 218 high scorers in the clinic, most [158 (72.5%), 95% confidence interval (CI) 66.6–78.4] scored high at reassessment. The mean fall in the HADS total score was 1.74 (95% CI 1.09–2.39), much of which could be attributed to the estimated change over time (regression to the mean) rather than the context.ConclusionsPre-consultation distress screening in clinic is widely used. Reassuringly, it only modestly overestimates distress measured later at home and consequently would result in a small proportion of unnecessary further assessments. We conclude it is a reasonable and convenient strategy.

Full text

Abstract:

Randomized response (RR) techniques are widely used in research involving sensitive variables, such as drugs, violence or crime, especially when a population mean or prevalence must be estimated. However, they are not generally applied to examine relationships between a sensitive variable and other characteristics. This type of technique was initially applied to qualitative variables, and studies later showed that a logistic regression may be performed with RR data. Since many of the variables considered in this context are quantitative, RR techniques were extended to these cases to estimate the values required. Regression analysis is a valuable statistical tool for exploring relationships among variables and for establishing associations between responses and covariates. In this article, we propose a design-based regression analysis for complex sample designs based on the unified RR approach. We present estimators of the regression coefficients, study their theoretical properties and consider different ways to estimate their variance. The properties of these estimation techniques were simulated using various quantitative randomized models. The method proposed was also used to analyse the findings from a real-world survey.

Abstract:

Purpose In this study, the authors examined diagnostic and intervention services for children identified with hearing loss (HL) after the newborn period. Method The authors compared ages at service delivery and length of delays between service delivery steps for 57 later-identified children with HL and 193 children who referred for assessment from the newborn hearing screen (NHS). For only later-identified children, regression models were used to investigate relationships among predictor variables and dependent variables related to service delivery. Results Children who referred from the NHS received follow-up services at younger ages than later-identified children. Later-identified children had significantly longer delays from HL confirmation to entry into early intervention, compared to children who referred from the NHS. For later-identified children, degree of HL predicted ages at follow-up clinical services. Children with more severe HL received services at younger ages compared to children with milder HL. Gender predicted the length of the delay from confirmation to entry into early intervention, with girls demonstrating shorter delays. Conclusions The current results lend support to the need for ongoing hearing monitoring programs after the neonatal period, particularly when children enter early intervention programs because of language/developmental delays.
