%description
Recursive partitioning methods to build classification trees for ordinal
responses within the CART framework. Trees are grown using the Generalized
Gini impurity function, where the misclassification costs are given by the
absolute or squared differences in scores assigned to the categories of
the response. Pruning is based on the total misclassification rate or on
the total misclassification cost.
