%description
Fast computing an ensemble of rank-based trees via boosting or random
forest on binary and multi-class problems. It converts continuous gene
expression profiles into ranked gene pairs, for which the variable
importance indices are computed and adopted for dimension reduction.
Decision rules can be extracted from trees.
