Abstract: Performs a CART (Classification and Regression Trees) analysis. This is a nonparametric alternative to regression for analyzing the relationship between a dependent variable and a set of explanatory variables. CART works by splitting off the data into branches based upon the values of the independent variables. At each stage, it takes the branch which has the highest within group sum of squares for the dependent variable, and picks a split point which gives the greatest reduction in that sum. The calculations required to create a CART are simple (nothing more than sums of squares), but tedious, as each value of each explanatory variable is examined at each stage.
