Abstract:

Coastal dolphins are often exposed to habitat degradation and direct interactions with humans. Major factors that influence dolphin distribution, critical for conservation concerns, are still poorly understood even for the bottlenose dolphin, the best-studied cetacean. To establish the environmental conditions that best predict occurrence of bottlenose dolphins and high feeding densities in Galveston Bay, I conducted a total of 367 boat surveys in five locations of the estuary, totaling 3,814.77 km of search effort. I counted groups of dolphins and measured surface water temperature, salinity,

Abstract:

Longitudinal studies rely on data collected at several occasions from a set of selected individuals. The purpose of these studies is to use a regression-type model to express a response variable as a function of explanatory variables, or covariates. In this thesis, we use marginal models for the analysis of such data, which, coupled with the method of estimating equations, provide estimators of the main regression parameter. When some of the responses are missing or there is error in the recorded covariates, the original estimating equation may be biased. We use techniques available in the lit

Abstract:

Bayesian Generalized Nonlinear Models (BGNLM) offer a flexible alternative to GLM while still providing better interpretability than machine learning techniques such as neural networks. In BGNLM, the methods of Bayesian Variable Selection and Model Averaging are applied in an extended GLM setting. Models are fitted to data using MCMC within a genetic framework in an algorithm called GMJMCMC. In this thesis, we present a new implementation of the algorithm as a package in the programming language R. We also present a novel algorithm called S-IRLS-SGD for estimating the MLE of a GLM by subsampli

My Masters research aims to deepen our understanding of the behaviour of robust methods in logistic regression. Logistic regression is a special case of Generalized Linear Modelling (GLM), which is a powerful and popular technique for modelling a large variety of data. Robust methods are useful in reducing the effect of outlying values in the response variable on parameter estimates. A literature survey shows that we are still at the beginning of being able to detect extreme observations in logistic regression analyses, to apply robust methods in logistic regression and to present informativel

Due to the rapid development and growing need for information technologies, more and more researchers start to focus on high-dimensional data.

Therefore, we propose a regularized efficient score estimation and testing (RESET) approach for treatment effects in the presence of nuisance parameters, either low-dimensi

Leaf morphology of Quercus (oak) species is highly variable and complicated confounded with phenotypic plasticity and fluctuating asymmetry (FA).

It was hypothesized that light exposure, individual trees, leaf position, and other leaf traits will influence variation in these species. Leaves were sampled from trees of these species and their morphological traits were measured. Absolute asymmetry

Abstract:

El tipo de cambio, visto como relación proporcional entre el valor de una moneda y otra es una variable macroeconómica importante de la economía globalizada, en el caso de México la paridad más importante que existe es la del peso (MXN) con respecto al dólar americano (USD) por la estrecha relación de intercambio comercial y de inversión que existe con los Estados Unidos. La variable es comparativa, una imagen útil para los hacedores de política y tomadores de decisiones en empresas privadas; repercute en la inflación, en el poder adquisitivo, golpea seriamente al comercio en mercados q

Abstract:

Denna kandidatexamen ligger inom området matematisk statistik. I samarbete med försäkringsbolaget Hedvig syftar denna avhandling till att utforska en ny metod för hantering av Hedvigs försäkringsdata genom att bygga en prissättningsmodell för alla riskförsäkringar med generaliserade linjära modeller. Två generaliserade linjära modeller byggdes, där den första förutspår frekvensen för ett anspråk och den andra förutspår svårighetsgraden. De ursprungliga uppgifterna delades in i 9 förklarande variabler. Båda modellerna inkluderade fem förklarande variabler i början och reducerades sedan. Minskni

Abstract:

A long record of daily data is used to study the lake levels of Lake Neusiedl, a large steppe lake at the eastern border of Austria. Daily lake level changes are modeled as functions of precipitation, temperature, and wind conditions. The occurrence and the amount of daily precipitation are modeled with logistic regressions and generalized linear models.

Abstract:

A região central de Portugal representa o limite sul da distribuição dos dois ecótipos de Salmo trutta L, o residente (i.e., truta-de-rio) e o anádromo (i.e., truta-marisca). Para além dos constrangimentos a uma escala mais global que as espécies de peixes experienciam, como o aquecimento global, os rios dessa região estão severamente fragmentados pela presença de grandes barragens e pequeno-médios açudes, construídos maioritariamente para a produção de eletricidade e recolha de água para uso doméstico, industrial e para a agricultura.

Abstract:

O modelo de referência para dados de contagem é o modelo de Poisson. A principal característica do modelo de Poisson é a pressuposição de que a média e a variância são iguais. No entanto, essa relação de média-variância nem sempre ocorre em dados observacionais. Muitas vezes, a variância observada nos dados é maior do que a variância esperada, fenômeno este conhecido como superdispersão. O objetivo deste trabalho constitui-se na aplicação de modelos lineares generalizados, a fim de selecionar um modelo adequado para acomodar de forma satisfatória a superdispersão presente em dados de contagem.

Abstract:

Bien qu’il existe un large consensus de la communauté scientifique quant au rôle des indices acoustiques dans la compréhension de la parole, les mécanismes exacts permettant la transformation d’un flux acoustique continu en unités linguistiques élémentaires demeurent aujourd’hui largement méconnus. Ceci est en partie dû à l’absence d’une méthodologie efficace pour l’identification et la caractérisation des primitives auditives de la parole. Depuis les premières études de l’interface acoustico-phonétique par les Haskins Laboratories dans les années 50, différentes approches ont été proposées ;
