I have fitted a classification tree and I want to calculate the nodesizes, the nodeerror and the node probabilities (I am only interested in the terminal nodes). I have found those functions for the function classregtree but not for classificationtree.fit...I hope some of you can help me

Type 'help ClassificationTree' (or 'doc ClassificationTree'). You will see all methods and properties of a ClassificationTree object returned by ClassificationTree.fit.
