EM Imputation is available in SAS, Stata, R, and SPSS Missing Values Analysis module. Approaches to Missing Data: the Good, the Bad, and the Unthinkable Learn the different methods for dealing with missing data and how they work in different missing data situations. Take Me to The Video!
In particular, a model for the complete data is not required in the imputation step, and the complete data method used after the imputation may be a general estimating equation for estimating a finite-dimensional parameter. Large sample results for the resulting estimator are given....
In a previous work, it was clearly shown that the performance of the very simple imputation method based on Most Common Attribute Value called MC gave performance better than that of several complex imputation algorithms. And in that work [1] it was shown that the performance of MC was ...

Missing values for smoking, CD4 count, viral load, and BMI were imputed using multiple imputation by chained equations which assumes data are missing at random. CD4 count, viral load and BMI were imputed as continuous variables and then categorized. All covariates were selected a priori based on...

One method is to include the inverse of the propensity score as a linear term in the imputation model [D. Firth and K.E. Bennett, Robust models in probability sampling, J. R. Statist. Soc. Ser. B. 60 (1998), pp. 321; D.O. Scharfstein, A. Rotnitzky, and J.M. Robins, ...
