This study reviewed recent advances in the diagnosis of and corrections for "sample selection bias."
Sampling has long been central in discussions of sociological research methods. Yet, with few exceptions, recent developments on the nature of sampling bias have not filtered into sociological practice. This neglect represents a major oversight with potentially dramatic consequences since internal as well as external validity is threatened. In response, this paper undertakes a brief review of recent advances in the diagnosis of and corrections for "sample selection bias." (Published Abstract)
