To be honest I've never heard of Proc Treeboost before but there's another paper here with some documentation and discussion about it http://support.sas.com/resources/papers/proceedings17/0847-2017.pdf

Thanks ! The PROC TREEBOOST is supposed to be the procedure used by the Gradient Boosting node in Enterprise Miner (EM), but I need to automate the optimization of its parameters using SAS code to avoid doing it manually from EM, ie.: search over a combination of ITERATIONS, SHRINKAGE, TRAINPROPORTION, etc. values from a SAS macro, instead of changing values from the node properties window in EM and running the flow manually each time I change a setting.
I will contact the the authors of the paper you're referring to to understand where did they get the specification of PROC TREEBOOST from; there are several properties of the EM Gradient Boosting node not used/mentioned in the paper.
It's really strange this procedure PROC TREEBOOST is not in the official SAS documentation.
