Try commenting the above code, every line, with what you expect and repost.

Pay attention to where your macro variables are, a macro variable inside a macro is a local macro variable and does not exist outside the macro (for example &pt). You have two macro variables, &pt and &u, are each where you expect them to be?

Thanks .This is what I have:

%macro pat(patt=);

%do pt=1 %to &patt;

data Pattern_&pt;

age=0;

output;

run;

%end;

%mend pat;

%MACRO DO_BRANCH(replicates=);

%do u=1 %to &replicates;

proc surveyselect data=new method = urs sampsize = 141 OUTHITS

reps=1 seed=1234100 out=new_&u;

run;

%pat(patt=2);

ods trace on /listing;

ods graphics on;

ods output ParameterEstimates=CPHH_&u;

proc phreg data=new_&u ;

model monset*obs(0)=age;

*baseline out=survs survival= survival;

baseline covariates=Pattern_&pt out=survs_&u survival= survival;

run;

CODES>>>>>>>

%end;

%MEND DO_BRANCH;

This does not work

%DO_BRANCH(replicates=2);

You're stilling mixing up your macro variables. &pt and &u.

Re: PHREG baseline survival estimates.

desireatem — Fri, 17 Jan 2014 15:38:48 GMT

I do not know how I am mixing them up both are 2. Can you help show me how to correct it so that I do not mix them up

Re: PHREG baseline survival estimates.

Reeza — Fri, 17 Jan 2014 15:45:09 GMT

But, do they both exist? And are you using &pt when you should be using &u? And where is &u defined or assigned.

I have commented the code place it back, can anyone help
