www.pharmasug.orgFor the purposes of this paper, all data values in Study Data Tabulation Model (SDTM) datasets are considered to be observed. This is despite the fact that in actuality a data value may have been derived prior to or during the creation of the SDTM datasets. For example, an SDTM value of LDL cholesterol derived by the Friedewald calculation from

Multiple Imputation of Missing Data Using Stata
dss.princeton.eduimputation 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.
