Have you looked at examples in documentation?

I think the third one is applicable.

Hi Reeza,

Thanks for the link. Can you please clarify one more thing. Like we use class statement in our 'proc logistic' procedure (to specify our categorical variables used in model statement). Do we have to do the same in 'proc phreg' also? And, do it serves the same purpose 'specify our categorical variables used in model statement'?

Thanks!

Yes, you use the CLASS statement in PROC PHREG similar to how you would in PROC LOGISTIC

Not sure what that means. You still have to list the categorical variables in both your CLASS and MODEL statements.

Thanks! your answer clarifies my last question. Can you suggest/answer my one question (as I am not sure)

As per standard practice: Can we include continuous variable specially 'Age' on RHS of = sign (i.e. independent variable) in model statement for PHREG procedure?

I am asking this because I am not a statistician.

My personal suggestion, don't run a proc if you don't know what it does, especially the statistical procedures.

Yes, continuous and categorical variables can go into a model.
