Abstract: We discuss issues arising from methodological developments related to inverse probability weighting and model-based prediction with non-probability survey samples, with focuses on the validity of estimation procedures for participation probabilities (propensity scores) and the impact of key assumptions on inferential approaches. We also explore strategies for dealing with undercoverage problems due to violations of the positivity assumption.
