Jonathan Sterne and colleagues describe the appropriate use and reporting of the multiple imputation approach to dealing with them Missing data are unavoidable in epidemiological and clinical research but their
Multiple imputation for missing data is an attractive method for handling missing data in multivariate analysis. The idea of multiple imputation for missing data was first proposed by Rubin (1977). Procedure The following is the procedure for conducting the multiple imputation for missing data that ...

The MNAR statement imputes missing values by using the pattern-mixture model approach, assuming the missing data are missing not at random (MNAR), which is described in the section Multiple Imputation with Pattern-Mixture Models. By comparing inferential results for these values to results for impu...

that properly reflect the uncertainty that results from missing values, such as valid confidence intervals for parameters. Multiple imputation inference involves three distinct phases: 1. The missing data are filled in m times to generate m complete data sets. ...
Rationale, aims, and objectives: Missing data represent a challenge in longitudinal studies. The aim of the study is to compare the performance of the multivariate normal imputation and the fully conditional specification methods, using real data set with missing data partially completed 2 years ...
