%description
Multiple Imputation has been shown to be a flexible method to impute
missing values by Van Buuren (2007) <doi:10.1177/0962280206074463>.
Expanding on this, random forests have been shown to be an accurate model
by Stekhoven and Buhlmann <arXiv:1105.0828> to impute missing values in
datasets. They have the added benefits of returning out of bag error and
variable importance estimates, as well as being simple to run in parallel.
