Fractional Imputation for Ordinal and Mixed-type Responses with Missing Observations
(University of Waterloo, 2017-01-12)This thesis addresses two essential aspects of large scale public-use data files involving ordinal and mixed-type responses with missing observations: (i) the creation of single complete data sets with imputation for missing ... -
Multiply Robust Empirical Likelihood Inference for Missing Data and Causal Inference Problems
(University of Waterloo, 2019-06-06)Missing data are ubiquitous in many social and medical studies. A naive complete-case (CC) analysis by simply ignoring the missing data commonly leads to invalid inferential results. This thesis aims to develop statistical ... -
Semiparametric Empirical Likelihood Inference under Two-sample Density Ratio Models
(University of Waterloo, 2021-08-27)The semiparametric density ratio model (DRM) provides a flexible and useful platform for combining information from multiple sources. It has been widely used in many fields. This thesis considers several important inference ... -
Statistical Analysis with Non-probability Survey Samples
(University of Waterloo, 2020-09-25)The goal of this thesis is to develop inferential procedures with non-probability survey samples. In recent years, the use of non-probability survey samples has become one of the most important topics in the area. Contrast ...
