https://communities.sas.com/t5/SAS-Data-Science/HPforest-options-for-bagging/m-p/502759#M7406 <P>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.&nbsp; This is the "Proportion of Obs in Each Sample" property in the HP Forest node in Enterprise Miner.</P> Tue, 09 Oct 2018 15:34:33 GMT WendyCzika 2018-10-09T15:34:33Z https://communities.sas.com/t5/SAS-Data-Science/HPforest-options-for-bagging/m-p/502634#M7404 <P>are the&nbsp; 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.</P> Tue, 09 Oct 2018 10:03:31 GMT https://communities.sas.com/t5/SAS-Data-Science/HPforest-options-for-bagging/m-p/502634#M7404 jitb 2018-10-09T10:03:31Z https://communities.sas.com/t5/SAS-Data-Science/HPforest-options-for-bagging/m-p/502759#M7406 <P>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.&nbsp; This is the "Proportion of Obs in Each Sample" property in the HP Forest node in Enterprise Miner.</P> Tue, 09 Oct 2018 15:34:33 GMT https://communities.sas.com/t5/SAS-Data-Science/HPforest-options-for-bagging/m-p/502759#M7406 WendyCzika 2018-10-09T15:34:33Z https://communities.sas.com/t5/SAS-Data-Science/HPforest-options-for-bagging/m-p/502790#M7407 <P>Thank you, Wendy. Was getting a bit confused on this. You cleared it up for me.
