⚠️There's a newer version (3.17-44) of this package.Take me there.

miceadds (version 1.4-0)

Some Additional Multiple Imputation Functions, Especially for 'mice'

Description

Contains some auxiliary functions for multiple imputation which complements existing functionality in R. In addition to some utility functions, main features include plausible value imputation, multilevel imputation functions, imputation using partial least squares (PLS) for high dimensional predictors, nested multiple imputation, and two-way imputation.
