Scoring Cox Model - PHREG

I have 2 doubts:

1- I would like to confirm if I can score a data automatically using the following code:

PROC PHREG DATA = DATA_TRAINING NOPRINT;

     MODEL TIME*C_VAR(0) = var1 var2 var3;

     BASELINE OUT= DATA_SCORED COVARIATES= DATA_TO_SCORE SURVIVAL=SURV;

RUN;

DATA_TRAINING=> Database that I have responses and I will take the estimators;

DATA_TO_SCORE => Database that I want to score using estimators calculated with DATA_TRAINING;

DATA_SCORED => Output data (DATA_TO_SCORE scored).

 

2- I would like to know how to score a data creating a code writting all estimators manually:

score = s(t) ** exp(sum(var1*est1, var2*est2, var3*est3))

How do I get this s(t) in DATA_TRAINING?

 

Thanks in advance
