The laplace approximation and inference in generalized linear models with two or more random effects

Creator:: Pratt, James L.
Abstract:: This thesis proposes an approximate maximum likelihood estimator and likelihood ratio test for parameters in a generalized linear model when two or more random effects are present. Substantial progress in parameter estimation for such models has been made with methods involving generalized least squares based on the approximate marginal mean...

Chemical and physical influences of the atmosphere upon the spatial and temporal characteristics of atomic fluorescence in laser microprobe plumes

Creator:: Lewis, Arnold Leroy
Abstract:: The temporal and spatial characteristics of the plume produced by a laser microprobe, are dependent upon the composition and pressure of the atmosphere surrounding it. It has been shown that certain atmospheres can enhance the analytical signal by increasing the free atom lifetime. Improvements were made to the existing laser...

Extensions for paired comparisons models

Creator:: Kolsky, James D.
Abstract:: The Thurstone-Mosteller and Bradley-Terry Models are commonly used to rank items from paired comparisons experiments in which one item in each pair "wins," and to assess the importance of time-independent explanatory variables on such rankings. The first part of this thesis clarifies the use of probit and logistic regression models...

Diagnostic tools for overdispersion in generalized linear models

Creator:: Ganio-Gibbons, Lisa M.
Abstract:: Data in the form of counts or proportions often exhibit more variability than that predicted by a Poisson or binomial distribution. Many different models have been proposed to account for extra-Poisson or extra-binomial variation. A simple model includes a single heterogeneity factor (dispersion parameter) in the variance. Other models that...

Selection on larval and adult body size in a marine fish: potential evolutionary responses and effects on population dynamics

Creator:: Johnson, Darren W.
Abstract:: Many species have complex life cycles in which a dispersive larval stage is followed by a relatively sedentary adult stage. For such species, reproductive output is often high and large variation in survivorship throughout early life-history phases (eggs and larvae) can lead to dramatic fluctuations in recruitment which may in...

Statistical analysis of RNA sequencing count data

Creator:: Mi, Gu
Abstract:: RNA-Sequencing (RNA-Seq) has rapidly become the de facto technique in transcriptome studies. However, established statistical methods for analyzing experimental and observational microarray studies need to be revised or completely re-invented to accommodate RNA-Seq data's unique characteristics. In this dissertation, we focus on statistical analyses performed at two particular stages in...

Using the Microbial Tree of Life to Describe Mammalian Health and Disease

Creator:: Arnold, Holly Kristin
Abstract:: The past decade of research has potentiated a revolution in our understanding of mammalian health and evolution by revealing that the gut microbiome plays a central role in mammalian physiology. Our ability to unlock this potential hinges upon the identification of specific groups of gut microbes that elicit effects on...

Pharmacokinetic modeling and simulations of gastrointestinal transit effects on drug pharmacokinetics from enteric-coated pellet formulations and their applications

Creator:: Watanalumlerd, Prapoch
Abstract:: Effects of gastrointestinal transit on plasma concentrations of drugs from enteric-coated pellet formulations were demonstrated using pharmacokinetic models describing plasma concentrations of drugs from various enteric-coated pellet formulations. Gastric emptying time, lag time of emptying, and drug release rate from pellets in the small intestine, along with other pharmacokinetic parameters...
