The exact bias of the multiple imputation variance estimator is presented. A method of reducing the bias is presented and simulation is used to make comparisons. We also show that the suggested method can be used for a general class of linear estimators.Statistics Theory62D05 (Primary) 62J99 (Secondary)text
