Webb19 nov. 2015 · However, when I extract the scoring code to run the forest in Base SAS, I see that a lot of these variables that I don't want in the model are still run in the SAS code? Is this just the way the random forest node executes? Are these variables used in the final model anyways (which is not ideal)? Thanks for the help! J 0 Likes Webbdocumentation.sas.com
