PROC TREE: PROC TREE Statement :: SAS/STAT(R) 9.2 User

WebbTree boosting creates a series of decision trees that form a single predictive model. Like decision trees, boosting makes no assumptions about the distribution of the data. Boosting is less prone to overfit the data than a single decision tree. If a decision tree fits the data fairly well, then boosting often improves the fit. WebbThe PROC TREE statement starts the TREE procedure. The options that can appear in the PROC TREE statement are summarized in Table 91.1.
