Abstract:

Functional Principal Component Analysis (FPCA) is an important dimension reduction technique to interpret the main modes of functional data variation in terms of a small set of uncorrelated variables. The principal components can not always be simply interpreted and rotation is one of the main solutions to improve the interpretation. In this paper, two new functional Varimax rotation approaches are introduced. They are based on the equivalence between FPCA of basis expansion of the sample curves and Principal Component Analysis (PCA) of a transformation of the matrix of basis coefficients. The

Abstract:

Abstract. Global seismic tomography has greatly progressed in the past decades, with many global Earth models being produced by different research groups. Objective, statistical methods are crucial for the quantitative interpretation of the large amount of information encapsulated by the models and for unbiased model comparisons. Here we propose using a rotated version of principal component analysis (PCA) to compress the information in order to ease the geological interpretation and model comparison. The method generates between 7 and 15 principal components (PCs) for each of the seven tested

Abstract:

Responses of 392 New Zealand subjects to the Eysenck Personality Inventory were subjected to second, third and fourth-order principal components analysis. Subsequently, the results obtained from two and three-factor, fourth-order varimax rotations were compared with each other when appropriate with equivalent first-order solutions obtained from the same previously published data. It is concluded that the nature of the solutions found is more a function of the number of factors rotated than of the level at which rotation takes place, even in the virtually untrodden realms of fourth-order analys

Abstract:

In this chapter a digital assessment and an associated novel mathematical statistical model are provided as online psychometrics designed to evaluate College and University courses. The psychometric evaluation tool is a Student Ratings of Instruction [SRI] instrument used at a Historically Black College and University [HBCU] for course evaluation purposes. The research methodology is an a posteriori post hoc investigation that examines the reliability and validity of the items used in the SRI instrument. The sample under analysis consisted of the responses to 56,451 total items extracted from 7,919 distributed Student Ratings Instruments delivered online during the 2012 academic year. The post hoc application of the novel Tri–Squared Test analysis methodology is used to intricately analyze the results of an earlier study on SRIs that yielded strong construct validity from Cronbach's Alpha Reliability Model, Goodman & Kruskal's Lambda, and Principal Component Factor Analysis with Varimax Rotation.

Abstract:

Universities impact in the entrepreneurship ecosystem, they emanate a large number of talents, using their resources to support entrepreneurship. From this situation, arrives the importance of generating and validating measurement instruments to contribute to the identification of level of entrepreneurial intention with which students, of higher education level, have. The Exploratory Factor Analysis technique, uses the Varimax Orthogonal Rotation method, with principal component extraction factors, with a sample of 235 students in public universities of the state of Guanajuato in Mexico, considering 6 dimensions as variables. The results of this research consider as relevant only 3 dimensions from the 6 studied, considering that the entrepreneurial intention in the higher education student is a product of creativity, innovation and need for achievement. While the three dimensions: self-esteem, assumption of risk and problem solving, does not reach a relevant importance; showing a robust instrument for the Mexican context.

Abstract:

A recent presidential directive mandated that all U.S. government agencies establish a centralized identification system. This study investigated the impact of users’ involvement, resistance, and computer self-efficacy on the implementation success of a centralized identification system. Information System (IS) usage was the construct employed to measure IS implementation success. A survey instrument was developed based on existing measures from key IS literature. The results of this study indicated a strong reliability for the measures of all constructs (user involvement, computer self-efficacy, user’s resistance, and IS usage). Factor analysis was conducted using Principal Component Analysis (PCA) with Varimax rotation. Results of the PCA indicate that items of the constructs measured had high validity, while Cronbach’s Alpha for each factor demonstrates high reliability for all constructs measured. Additionally, results of a structural equations modeling analysis using Partial Least Square (PLS) indicate that computer self-efficacy and user involvement had positive significant impact on the implementation success. However, the results also demonstrated that user’s resistance had no significant impact on IS usage, while end user involvement had a strong negative impact on user’s resistance.

Abstract:

The focus of this paper is on the synthesis of path generation mechanisms based on shape optimization. The principle component analysis (PCA) technique used in image processing is employed to represent the desired coupler curve of the mechanism and simulated annealing is used as the optimization tool. PCA representation is invariant under rotation, translation, scaling, and starting point. Once a shape-optimized mechanism is found, it is translated, rotated, and scaled to its final form. An illustrative example is introduced to demonstrate the proposed method.

Among them we chose and translated the Postpartum Bonding Questionnaire by Brockington et al. (2001) into Slovak language. The aim of this study was to analyse its psychometric qualities. Our non-clinical sample consisted of women (N= 372) 18 and 44 years (M= 29.74; SD= 5.25) who recently gave birth in Slovakian hospitals.
