I am using EG and I am consistently running into this error with hpsplit: ERROR: HPSPLIT stopped due to an internal error (0xF307)   I cannot diagnose the source of the error. This is the only error message it gives. So, it is hard to troubleshoot with little details. I am trying to create trees for a predictor by a variable. I know that hpsplit does not have by statement. I have a macro to take care of that but that is not issue. The subset data returns the error, but using the full dataset (as a test to see if hpsplit is corrupted or not) works fine.   From the output of the subset, I can get the Tree Performance and the variable importance. However, it will not output the predictions from the score-statement(which is what I need). I have googled around to try to find information on the error. I have not found anything on it. So I thought I would post and see if anyone has ran into problem and found a solution(or workaround).   I wish I could provide more details but it is confidental information.   Any help will be appriciated ...
