New robust tree-based procedures are described, which are obtained by introducing in the tree building phase some objective functions already used in the linear robust regression approach, namely Huber’s and Tukey’s bisquare functions. The performance of the new procedures is evaluated through a Monte Carlo experiment.}, number={2}, journal={Statistica}, author={Galimberti, Giuliano and Pillati, Marilena and Soffritti, Gabriele}, year={2007}, month={Jan.}, pages={173–190} }
