How do you code for 1-sided (side=U) in proc glm?

Hi guys, below is my proc phreg model snapshot.

Do you know how to define two-tailed test? so that my Pr>ChiSq in the SAS output is adjusted to two-tailed test? Or would you recommend just halving P value for two-tailed adjustment?

proc phreg data=p.temp2;
	class A10(ref='30-39') combo1(ref='0') combo2(ref='0') ....
/param=ref order=internal;

model duration*vital_status(1)=combo1 combo2 .../ties=Efron rl;

run;

So your title asks about GLM but your example uses PHREG? What are you really asking?

It's really weird, my title is changed to a Title of previous post that I was looking at. My intended title is exactly what I'm asking in the post. "How to specify the test is two-tailed in PROC PHREG"

Try to make a new thread with the desired title.

Or, even better, just stick to the existing thread with the correct title that you started on the appropriate board (SAS Statistical Procedures) about eight hours earlier.
