This paper provides a statistical testing approach to the validation of the pruning process in regression trees construction. In particular, the testing procedure, based on the F distribution, is applied to the CART sequence of pruned subtrees providing a single tree prediction rule which is statistically reliable and might not coincide with any tree in the sequence.
