PROC HPSPLIT Decision Tree - Showing Full Decision Tree

Hi all,

I am currently working on a project that requires me to do some classification, so I thought of PROC HPSPLIT. Particularly, I am interested to look at the subtree that it produced. However, as I am working on 5 different variables and there is one nominal variable (account) that has about 100 levels, it seems that the subtree outcome was only shown for the first three decisions. Is there a way that the PROC HPSPLIT can return me with a complete decision tree?

proc hpsplit data=data.trial1 seed=123;
class ATT_Type account att_war_d;
model ln_eq_sales=ln_eq_price ATT_Type account att_war_d ln_cost ln_btu;
run;

Your guidance will be much appreciated. Thank you in advance and have a good day.

Best,
David

I think I know what you're asking about, but not 100% sure so if you could include a screenshot, that would be helpful.

If it's about how sometimes you only see part of the rule in the HP Tree results in the Tree plot, with a "..." at the end, in that case you might have to look at the score code or Node Rules to see the entire rule.
