Missing data in electronic health records

This Stata program uses the two-fold fully conditional specification (FCS) algorithm to impute missing values in longitudinal databases. More information and installation details are available here, and a blog post on handling missing data in longitudinal clinical databases is available here.

A paper describing the 'twofold' command entitled "Application of multiple imputation using the two-fold fully conditional specification algorithm in longitudinal clinical data" has been published in The Stata Journal.

A paper describing a study validating the two-fold fully conditional specification algorithm using simulated data was accepted for publication in Statistics in Medicine.
