Multiple imputation is a method specifically designed for variance estimation in the presence of missing data. Rubin …'s combination formula requires that the imputation method is "proper" which essentially means that the imputations are random draws …, the methods used for imputing for nonresponse are typically non-Bayesian, e.g., some kind of stratified hot-deck.
