HPforest options for bagging

[jitb]

are the  trainfraction and inbagfraction options in proc hpforest statement the same? I just wanted to know the theory behind using these options. I'm assuming the inbagfraction ratio is used to do the bagging from the training data. Does the trainfraction ratio I give do the same thing too? Thanks.

Yes, you're correct - the INBAGFRACTION and TRAINFRACTION in PROC HPFOREST are the same thing - the fraction of training obs. to train a tree with.  This is the "Proportion of Obs in Each Sample" property in the HP Forest node in Enterprise Miner.

Thank you, Wendy. Was getting a bit confused on this. You cleared it up for me. Thanks again.
