Partition Platform

The Partition platform recursively partitions the predictors (Xs) to develop a predictive model for Y. At

each step, the platform finds two intervals of values for a continuous X or two sets of levels for a cate-

gorical X that best predict Y. It does this by exhaustively searching all possible splits. These splits of the

X variables are performed recursively, resulting in a decision tree. The tree defines decision rules that

determine a predictive model based on the optimum splits.
