WebDecision trees are trained by passing data down from a root node to leaves. The data is repeatedly split according to predictor variables so that child nodes are more “pure” (i.e., … WebDecision Tree Analysis is a general, predictive modelling tool that has applications spanning a number of different areas. In general, decision trees are constructed via an algorithmic approach that identifies ways to split a data set based on different conditions. It is one of the most widely used and practical methods for supervised learning.
