Abstract
Multiple imputation for partially observed data with survey weights has been criticized, because Rubin's variance formula may be invalid. Focusing on a regression setting, we discuss this criticism, and argue that multilevel imputation can address some of the issues. We illustrate with some simulations and an analysis of the Youth Cohort Study.
