How does one define a split criteria for a decision tree in SAS or SAS EM ?
I'm trying to figure out uplift/netlift modeling, but none of the tools in SAS seem extensible enough to instantiate a prototype split
I remember once using PROC SPLIT to do something I beleive is what you are trying to describe. It is part of SAS/EM. This was a very long time ago however and I am no longer a user of this product.
I've been looking into proc split, but I don't see an option to change/customize the split logic. Thanks for the note.
