Does PREDICT have the ability to prune trees within models to avoid over fitting. I found this article which talks about this. http://www.statmethods.net/advstats/cart.html

Trees in LityxIQ are automatically pruned to avoid over-fitting (i.e., the underlying algorithm will build a bigger tree, then use internal cross-validation to prune it back to a more stable level), in addition to being able to directly control over-fitting using the options Simon mentioned. PREDICT doesn’t allow you to manually pick a node and prune it off.
