Proc TRANSREG for conjoint analysis - how to disable intercept?

I tried to use proc transreg to do a conjoint analysis. Due to the design problem, I have to fit the model without the intercept. I tried below code:

proc transreg data=test1 utilities short;
model identity(y) = class(f1 f2 f3 / zero=sum)/noint;
output out=test2;
run;

It always had below note in SAS log:
NOTE: NOINT is only valid when there is no implicit intercept and when no variables are iteratively transformed.
NOTE: The NOINT option will be ignored.

The results still have the intercept.

Anybody know how to disable intercept fitting? Thanks Message was edited by: ffang
