Multiple Imputation of Missing Data Using Stata

imputation model should always include all the variables in the analysis model, including the dependent variable of the analytic model as well as any other variables that may provide information about the probability of missigness, or about the true value of the missing data. Theory should guide the decision as to which variables to include.
