Proc HPForest

Hi All,

When we execute Proc HPForest in SAS studio results show fitstats for training & Out of Bag(OOB) observations whereas in SAS Eminer results show fitstats for training,OOB and for validation datasets. I'm just wondering why this difference and how can we get fitstats for validation dataset in SAS studio?

Regards

You would need to have a partition indicator in your data set that determines which observations are included for training and which for validation. For example for a variable with value 1 for the training observations and 0 for the validation observations, you can use the PARTITION statement in PROC HPFOREST:

partition rolevar=Name-of-your-partition-variable (train='1' validate='0');

Hi Wendy,

Thanks for the reply. Still not getting the validation part in fitstats. I've attached the screen shot.

Thanks,

Try with Validate in place of Test on your PARTITION statement. I don't think a test partition is supported.
