Title: Statistical Inference With Non-Probability Survey Samples (Author: Changbao Wu)

Abstract: We provide a critical review and some extended discussions on theoretical and practical issues with analysis of non-probability survey samples. We attempt to present rigorous inferential frameworks and valid statistical procedures under commonly used assumptions, and address issues on the justification and verification of assumptions in practical applications. Some current methodological developments are showcased, and problems which require further investigation are mentioned. While the focus of the paper is on nonprobability samples, the essential role of probability survey samples with rich and relevant information on auxiliary variables is highlighted.
