It consistsof three parts. The first part of this dissertation is Bayesian semi-parametric mediationanalysis for survival outcome with incomplete mediator. This work extends (Huang et al.,2004) approach to causal mediation analyses, addresses model misspecification problem thatwas inherited in the commonly used method (Lin et al., 1997); in addition, it solves the issuesof missing mediator under the assumption of MCAR or MAR. The second part considers theproblem of assessing mediation effect when both outcome and mediator are censored. Thisproblem is tackled by developing an informative missing data imputation modeling for thecensored mediator, and develop a Markov Chain Monte Carlo algorithm to obtain posteriorestimates. The third part considers longitudinal mediator problem. The previous work(Taylor et al., 1998, 2001) is extended on joint modeling of longitudinal mediator and thesurvival outcome. For the longitudinal modeling of mediator, the proposed model considersfixed effects, random effects, and a specified stochastic process with measurement error usingDirichlet process priors on the coefficient parameters. 2011-09-23 English text University of Cincinnati / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ucin1313684054 http://rave.ohiolink.edu/etdc/view?acc_num=ucin1313684054 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
