Abstract
Recent developments in survey statistics have yielded simple, novel measures of the non-ignorable selection bias in estimates of means, proportions, and regression coefficients that may arise due to deviations from ignorable sample selection, where these deviations might be introduced by the sampling mechanism (e.g., non-probability sampling) or survey nonresponse. This presentation will review the computation of these indicators, the data required to compute them, software tools for computing them, and examples of their use and interpretation based on real survey data. Future directions for research in this area, including ongoing work to assess selection bias in the 2020 presidential election polls, will be provided in conclusion.
