Cutpoint-based grouping strategy (regression).

Creates a grouping strategy for regression trees: observations are split by the cutpoint in projected space, then each child's observations are sorted by the continuous response and median-split into 2 new groups for the next projection-pursuit step. This is the default grouping strategy for regression.

Usage

grouping_by_cutpoint()

A grouping_strategy object.
