Hi James, I'd like to use HPSPLIT to illustrate a decision tree based on five categorical variables, the last level as the outcome. Let's call them Level1 through Level5 (outcome). To illustrate the null case or arrangement, I would like to force SAS to use a specific order of variables ending with the outcome variable. Is it possible to force SAS into following a specific order of variables for several levels in HPSPLIT before I begin entropy testing and scoring? Thank you.
