Decision tree splitting rule in SAS EM

[ycenycute]

In the decision tree node property panel, we can choose splitting rule for nomial target and ordinal target. I am wondering if my target is set to binary and I would like to use gini gain, shall I change nominal target to gini or ordinal target to gini?

Binary target needs to be treated as nominal target. Choose Gini index with Nominal target.

Do I need to change binary target to nominal target first? Or shall I directly pick gini index with nomial target?

[gcjfernandez]

You can directly pick Gini index.
