Bayesian Semiparametric Quantile Regression For Clustered Data, Xin Tong
Bayesian Semiparametric Quantile Regression For Clustered Data, Xin Tong
Theses and Dissertations
Traditional frequentist quantile regression makes few assumptions on the form of the error distribution and thus is able to accommodate non-normal errors. However, inference on the quantile regression models could be challenging for the unknown error distribution, though asymptotic or resampling methods were developed. Bayesian literature on quantile regression with random effects is relatively limited. The quantile regression approach proposed in this dissertation is founded on Bayesian probabilistic modeling for the underlying unknown distributions. By adopting the error density with a nonparametric scale mixture models, we developed Bayesian semiparametric models to make an inference on any quantile of interest and …

Cancer Health Literacy And Hospitalization In The First Five Years Following A Cancer Diagnosis, Laura A. Cartwright
Theses and Dissertations
BACKGROUND: The field of health literacy research has been focused recently on developing more accurate measurement tools and understanding the relationship between health literacy and health outcomes. Individuals with lower levels of health literacy have worse health outcomes, including hospitalization rates, compared to those with adequate health literacy. This relationship has yet to be examined in the cancer patient population, although significant relationships between health literacy and cancer knowledge, screening behavior and quality of life have been found. This study is the first to examine the relationship between health literacy and hospitalization rates in a cancer patient population, and the …
