Hua:
SAS/EM aside, the JMP product includes impressive recursive partitioning programs with equally impressive graphics support. The JMP product requires an additional licensing fee, but not one of the order of SAS/EM.

The Salford Systems TreeNet program reads SAS datasets and provides direct support for classification and regression trees. Licensing costs tend to be moderate, and the Salford free trial of the program helps you decide if it's worth the cost.

Does SAS have a procedure for "classification and regression tree or recursive portioning analysis".   I noticed SAS has a TREE procedure as part of cluster analysis, which is not what I am talking about here.

Thank you very  much for your insight!
