Inference for domains under imputation for missing survey data

摘要

Two different approaches to inference are used: 1. Design-based with uniform response within classes. 2. Model-assisted with ignorable response and an imputation model. The imputed domain estimators are biased under (1), but approximately unbiased under (2). A bias-adjusted estimator is obtained that is approximately unbiased under (1) or (2). (9 refs.)
