Webb19 mars 2004 · 2. Recursive partitioning and genotype groups 2.1. Recursive partitioning. RP is an approach to identifying important predictors among a large number of covariates with high order interactions. In this paper we focus on the least squares criterion for arriving at the best split of the data. Other criteria have been proposed which could be … Webb6 jan. 2011 · Classification and regression trees are machine-learning methods for constructing prediction models from data. The models are obtained by recursively partitioning the data space and fitting a simple prediction model within each partition. As a result, the partitioning can be represented graphically as a decision tree.
