Substituting missing values using the mice package

Finding and removing missing values in your dataset is not always a viable alternative, for either operative or methodological reasons. It is often preferable to simulate possible values for missing data and integrate those values within the observed data.

This recipe is based on the mice package by Stef van Buuren. It provides an efficient algorithm for missing value substitution based on the multiple imputation technique.
