PROC HPSPLIT Decision Tree

[WilliamB]

Hello,
I'd like to make a decision tree that starts with the 'age' variable and then processes the variable 'DebtRatio'.
And another decision tree that starts this time by 'DebtRatio' then 'age'.

Because I want only 2 split, I want to see the difference of decisions in these 2 cases.

How to do this?

Thanks for your help.

proc hpsplit data=train seed=15531 maxdepth=2 splitonce ;
model SeriousDlqin2yrs = DebtRatio age ;
grow Ftest;
prune costcomplexity;
code file='treesc.sas';
rules file='projetrules.txt';
output out = scoredtraining ;
run;
quit;

To be able to force particular splits, you would have to use the Interactive Decision Tree Application in the Decision Tree node in EM.  Only automated splitting is available in the HP Tree node / PROC HPSPLIT.
