Dear All,

It would be useful to have pruning cut of points estimated on the bases of a separate test set.

I think currently cross validation is used, so the tree is build using a n-1 folds, and then nodes in the tree get pruned away whether or not removing them increases accuracy on the nth fold.

Best regards,

Wessel
