Hi the code below gives the s_(t)=[s_(0)]^esp(beta *Av(age3)).
How do I modify the code to get the baseline survival at age3=0, that is just s_(0).
Below is the code that need to be fixed
ods trace on /listing;
ods output ParameterEstimates=CPHH;
proc phreg data=new ;
model monset*obs(0)= age3;
baseline out=survs survival= survival;
run;
ods trace off;
data Pattern;
Age=0;
output;
run;
ods trace on /listing;
ods output ParameterEstimates=CPHH;
proc phreg data=new ;
model monset*obs(0)= age;
baseline covariates=Pattern out=survs survival= survival;
run;
ods trace off;
data Pattern;
Age=0;
output;
run;
ods trace on /listing;
ods output ParameterEstimates=CPHH;
proc phreg data=new ;
model monset*obs(0)= age;
baseline covariates=Pattern out=survs survival= survival;
run;
ods trace off;
