Bayesian nonlinear methods for survival analysis and structural equation models
([University of MissouriColumbia], 2014)High dimensional data are more common nowadays, because the collection of such data becomes larger and more complex due to the technology advance of the computer science, biology, etc. The analysis of high dimensional data ... 
Bayesian variable selection in parametric and semiparametric high dimensional survival analysis
(University of MissouriColumbia, 2011)In this dissertation, we propose several Bayesian variable selection schemes for Bayesian parametric and semiparametric survival models for rightcensored survival data. In the rst chapter we introduce a special shrinkage ... 
Estimates of school productivity and implications for policy
(University of MissouriColumbia, 2007)School productivity was not perfectly estimated because of the sampling error and the measurement error. The traditional Ordinary Least Square (OLS) leaves the estimation of school productivity questionable. Moreover, ... 
Multiple imputation approaches to regression analysis of intervalcensored failure time data
(University of MissouriColumbia, 2009)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This dissertation discusses regression analysis of intervalcensored failure time data, which occur in many fields including demographical, epidemiological, ... 
Nonparametric analysis of intervalcensored failure time data
(University of MissouriColumbia, 2009)This thesis considers the problem of treatment comparisons when only intervalcensored failure time data are available. This type of data occurs frequently in clinical trials and other followup studies. We study several ... 
The nonparametric analysis of intervalcensored failure time data
(University of MissouriColumbia, 2013)By intervalcensored failure time data, we mean that the failure time of interest is observed to belong to some windows or intervals, instead of being known exactly. One would get an intervalcensored observation for a ... 
Nonparametric and semiparametric methods for intervalcensored failure time data
(University of MissouriColumbia, 2006)Intervalcensored failure time data commonly arise in followup studies such as clinical trials and epidemiology studies. By intervalcensored data, we mean that the failure time of interest is not completely observed. ... 
Regression analysis of clustered intervalcensored failure time data
(University of MissouriColumbia, 2012)Clustered failure time data occur when the failure times of interest are clustered into small groups, while interval censoring occurs when the event of interest cannot be observed directly and is only known to have occurred ... 
Regression analysis of clustered intervalcensored failure time data with informative cluster size
(University of MissouriColumbia, 2010)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Correlated or clustered failure time data often occur in many research fields including epidemiological, geographical, sociological and medical studies. ... 
Semiparametric regression analysis of intervalcensored failure time data
([University of MissouriColumbia], 2014)By intervalcensored data, we mean that the failure time of interest is known only to lie within an interval instead of being observed exactly. Many clinical trials and longitudinal studies may generate intervalcensored ... 
Semiparametric analysis of multivariate longitudinal data
(University of MissouriColumbia, 2008)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Longitudinal studies are conducted widely in fields such as agriculture and life sciences, business and industry, demography and other social sciences, ... 
Semiparametric analysis of panel count data
(University of MissouriColumbia, 2007)Panel count data often arise in long term studies that concern occurrence rates of certain recurrent events. In such studies, each subject is observed only at finite discrete time points instead of continuously, and only ... 
Semiparametric and nonparametric methods for the analysis of panel count data
(University of MissouriColumbia, 2013)Panel count data are one type of eventhistory data concerning recurrent events. Ideally for an eventhistory study, subjects should be monitored continuously, so for the events that may happen recurrently over time, the ... 
Semiparametric transformation models for panel count data
(University of MissouriColumbia, 2011)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Panel count data arise in event history studies. It may not be feasible to monitor subjects continuously and recurrent events can be observed only at ... 
Statistical analysis for survival data with missing information
(University of MissouriColumbia, 2009)As a branch of statistics, survival analysis, which is often referred to as "reliability theory" in engineering, has a long history. While in practical problems, some information might be missing. This dissertation discusses ... 
Statistical analysis of failure time data with missing information
(University of MissouriColumbia, 2009)Failure time data arise in many fields and can involve different types of censoring structures and missing information. We consider three cases: rightcensored data with missing censoring indicators, clustered current ... 
Statistical analysis of lengthbiased and rightcensored data
(University of MissouriColumbia, 2013)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Biased sampling arises when the observations are not randomly selected from the target population. When the sampling probability is proportional to the ... 
Statistical analysis of multivariate intervalcensored failure time data
(University of MissouriColumbia, 2006)Intervalcensored failure time data commonly arise in clinical trials and medical studies. In such studies, the failure time of interest is often not exactly observed, but known to fall within some interval. For multivariate ... 
Statistical analysis of multivariate intervalcensored failure time data
(University of MissouriColumbia, 2007)A voluminous literature on rightcensored failure time data has been developed in the past 30 years. Due to advances in biomedical research, interval censoring has become increasingly common in medical followup studies. ... 
Statistical image analysis of photoactivated localization microscopy
(University of MissouriColumbia, 2013)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Fluorescent microscopy is a traditional way of localizing the biological molecules in the living cells. However, the diffraction limit makes it difficult ...
