+values, particularly in the case of mixed-type data.  It uses a random forest
+trained on the observed values of a data matrix to predict the missing values.
+It can be used to impute continuous and/or categorical data, including complex
+interactions and non-linear relations.  It yields an @acronym{OOB, out-of-bag}
+imputation error estimate without the need of a test set or elaborate cross-
+validation.  It can be run in parallel to save computation time.")
