Dear all,
I'm interested in fitting a classification tree by using a user-specified
splitting criterion. If I am right, Tree package allows to use only "deviance"
or "gini" while rpart package offers "anova", "poisson", "class" or "exp". and
tries to make an intelligent guess if method is missing.
I also found that, in rpart, method can be a list of functions named init,
split and eval but I really don't know how can I do it. Does someone can
suggest me some documentation I can have a look do define my splitting
criterion and pass it to rpart ?
Thanks
Paolo
