Abstract: This dissertation develops new model-based approaches for analysis of sample survey data. The main focus of the thesis is to incorporate information available from external sources to improve estimation and inference for finite population quantities. If such information is utilized properly, it can improve point estimates and inferences. The dissertation addresses two general scenarios: survey data from unequal probability designs and surveys with nonresponse.
