Power Analysis For A Mixed Effects Logistic Regression Model, Yinmei Li
Power Analysis For A Mixed Effects Logistic Regression Model, Yinmei Li
LSU Doctoral Dissertations
In herd health studies, the mixed effects logistic regression model with random herd effects are commonly used for modeling clustered binary data. These models are well developed and widely used in the literature, among which is the logistic-normal regression model. In contrast to the rich literature in modeling methods, the sample size/power analysis methods for such mixed effects models are sparse. The sample size/power analysis method for the logistic-normal regression model is not readily available. This study is to develop a power analysis/sample size estimation method for the logistic-normal regression model. Extended from the sample size method for the likelihood …

The Epidemiology Of West Nile Virus In Louisiana, Karen Ruth Gruszynski
LSU Doctoral Dissertations
West Nile virus (WNV), a member of the genus Flavivirus transmitted by mosquitoes, first appeared in the New York in 1999. Within five years WNV was detected throughout the contiguous 48 states causing disease in reservoirs and accidental hosts alike. In Louisiana, WNV was first detected in 2001 with one human case, ten equine cases, and six dead birds reported. The introduction of WNV into Louisiana presented an unique opportunity to observe an emerging disease unfold, so a study was launched to gain insight into the epidemiology of WNV in Louisiana. The first component, an environmental predictive model for West …

Racial Disparities, Birth Outcomes, And Changing Demographics Of East Baton Rouge Parish, Louisiana, Misty D. Richard
LSU Doctoral Dissertations
Racial and socioeconomic disparities persist throughout the country regardless of which specific disparity is studied; however, some geographic regions experience more significant racial disparities. East Baton Rouge Parish, Louisiana has a large racial disparity among birth outcomes. Many factors impact the degree of racial disparities, some of which include racial segregation, isolation, or centralization, access to and quality of medical care, and factors of the neighborhood environment. EBRP has undergone dramatic shifts in the demographics of its residents. The purpose of this dissertation was to study the demographic changes in the population; as well as to study the disparities among …
