feature selection methods in sas em

Hi,

Could anyone please tell me which feature selection methods SAS enterprise miner supports and how can I use them?

I have examples like information gain, gain ratio, chi-square, variable clustering, correlation matrix, association rule mining using apriori algorithm, ensemble of randomized decision trees for determining feature importance, Fisher Score and top feature selection

Regards
