%description
Computes a novel variable importance for random forests: Impurity
reduction importance scores for out-of-bag (OOB) data complementing the
existing inbag Gini importance, see also <doi:
10.1080/03610926.2020.1764042>. The Gini impurities for inbag and OOB data
are combined in three different ways, after which the information gain is
computed at each split. This gain is aggregated for each split variable in
a tree and averaged across trees.
