Abstract

The introduction of a third stage in tree growing approach is suggested. The aim is to find a honest tree, that is, a tree which is not only understandable and accurate, but also statistically reliable. Testing procedures for both classification and regression trees are introduced. These procedures guide the search for those parts in tree structures which are statistically significant.
