WebGenerally mse works best, but see Ishwaran (2015) for details. Multivariate regression analysis: For multivariate regression responses, a composite normalized mean-squared error splitting rule is used. Classification analysis: The default rule is Gini index splitting gini (Breiman et al. 1984, Chapter 4.3). WebHemant Ishwaran, Michael S. Lauer, Eugene H. Blackstone, Min Lu, and Udaya. B.
