...a way to make it use the entropy impurity? The second and third question concern the output of the printcp() function. 2.) What exactly are the cps in that sense here? I assumed them to be the treshold complexity parameters as in Breiman et al., 1998, Section 3.3? Are they the same as the treshold niveaus of alpha? I have read somewhere that the cps here are the treshold alphas divided by the root node error. Is that true? 3.) How is rel error computed? I am supposed to evaluate the goodness of classification of of the CART method. Do you think rel error is a good measure for that? I'd be ver...
