Has anybody ever implemented in R the "generalized degree of freedom" proposed by Ye (1998) in JASA 93(441):120-131 ? I would like to use this method to calculate degrees of freedom of regression trees. Thanks in advance. Jean-Noel Candau INRA - Unit?? de Recherches Foresti??res M??diterran??ennes Avenue A.
