I was working on a homework problem with SAS macros and ran into some issues. Can someone help me troubleshoot the problem? Here is the homework problem:
A team of investigators conducted a longitudinal study over 6 study time points (0 months or “baseline”, 2 months, 4 months, 6 months, 8 months, and 10 months) of 100 patients with HIV to examine the relative efficacy of three treatment regimens in increasing CD4 counts: group=1, control; group=2, treatment with one drug per month; group=3, treatment with two drugs per month. The primary question of interest was to test whether or not the pattern of mean CD4 values over time was different across the 3 study groups.
The data is stored in a file called, “hivstudy_sum18.txt”, The data are in the file are arranged with multiple rows per subject in list format in the following order: patient ID; study month; CD4 count; group.
Here is the data from the text file:

Here is the specific homework question I had issues on:
Write and execute a SAS macro to generate models for the interaction of study month as a continuous variable and treatment group that use generalized estimating equations (GEE) in SAS for CD4 count as a continuous, dependent variable employing four different working correlation structures: independence (IND); exchangeable (EXCH); autoregressive-1 (AR(1)); and unstructured (UNSTR).
Here is my code for this particular problem:
filename HW12 'C:\Users\jackz\Desktop\SAS\hivstudy_sum18.txt';
*Part A: Reading in Data;
proc format;
value grpf 0='control group' 1='one drug per month' 2='two drugs per month';
run;
data one;

input id month CD4 grp @@;
label id='Patient ID'
month='Study Month'
CD4='CD4 Count'
grp='Study Group';
run;
*Printout of Dataset One;
title 'Printout of Dataset One';
proc print data=one;
run;
%macro exper(datain,idm, monthm, grpm, CD4m);
proc sort data=&datain;
by &idm &grpm;
run;
proc genmod data=&datain order=freq;

repeated subject=&idm/ within=&grp type=UNSTR corrw;
run;
%mend exper;
%exper(one, id, month, grp, CD4);
When I ran this code, I received these errors:

Can someone provide some hints as to where I went wrong? Thanks!
You want to learn a couple of tools for working with macros. You will get better debugging if setting some options prior to running a macro (and then turning them off). The two most commonly helpful are MPRINT and SYMBOLGEN for determining what code text s being created by the macro. Another is MLOGIC to see the results of macro logic tests.
Example:
Options mprint symbolgen;
%exper(one, id, month, grp, CD4);
Options nomprint nosymbolgen;
With that out of the way, examine:
%macro exper(datain,idm, monthm, grpm, CD4m); proc sort data=&datain; by &idm &grpm; run; proc genmod data=&datain order=freq; class &grpm &monthm &idm; model &CD4m=&monthm &grpm &grpm*&monthm/type3; repeated subject=&idm/ within=&grp type=ar(1) corrw; run;
You are using a macro variable &grp without defining it. If you are meaning to use the DATASET variable GRP then remove the & from all of the &grp (not the &grpm which you do define). If you mean that to be &grpm then make the spelling change.
If you had run the code with the MPRINT option you would have seen that the generated code looked something like:
repeated subject=id/ within= type=ar(1) corrw;
Which why the error is expected name. No value for the &grp meant no data set variable was used with the WITHIN= option.
The error message seems pretty clear to me
NOTE 137-205: Line generated by the invoked macro "EXPER". 1 proc sort data=&datain; by &idm &grpm; run; proc genmod data=&datain order=freq; class 1 ! &grpm &monthm &idm; model &CD4m=&monthm &grpm &grpm*&monthm/type3; repeated subject=&idm/ 1 ! within=&grp type=ar(1) corrw; run; proc genmod data=&datain order=freq; - 22 ERROR 22-322: Expecting a name.

WARNING: Apparent symbolic reference GRP not resolved.
The macro processor is complaining that the macro variable GRP is not defined.
And SAS is complaining that WITHIN=&grp is invalid syntax for the REPEATED statement of PROC GENMOD.
Your macro variable is missing the M.
The last one should be &grpM not &grp.

I was working on a homework problem with SAS macros and ran into some issues. Can someone help me troubleshoot the problem? Here is the homework problem:
A team of investigators conducted a longitudinal study over 6 study time points (0 months or “baseline”, 2 months, 4 months, 6 months, 8 months, and 10 months) of 100 patients with HIV to examine the relative efficacy of three treatment regimens in increasing CD4 counts: group=1, control; group=2, treatment with one drug per month; group=3, treatment with two drugs per month. The primary question of interest was to test whether or not the pattern of mean CD4 values over time was different across the 3 study groups.
The data is stored in a file called, “hivstudy_sum18.txt”, The data are in the file are arranged with multiple rows per subject in list format in the following order: patient ID; study month; CD4 count; group.
Here is the data from the text file:

Here is the specific homework question I had issues on:
Write and execute a SAS macro to generate models for the interaction of study month as a continuous variable and treatment group that use generalized estimating equations (GEE) in SAS for CD4 count as a continuous, dependent variable employing four different working correlation structures: independence (IND); exchangeable (EXCH); autoregressive-1 (AR(1)); and unstructured (UNSTR).
Here is my code for this particular problem:
filename HW12 'C:\Users\jackz\Desktop\SAS\hivstudy_sum18.txt'; *Part A: Reading in Data; proc format; value grpf 0='control group' 1='one drug per month' 2='two drugs per month'; run; data one; infile HW12; input id month CD4 grp @@; label id='Patient ID' month='Study Month' CD4='CD4 Count' grp='Study Group'; run; *Printout of Dataset One; title 'Printout of Dataset One'; proc print data=one; run; %macro exper(datain,idm, monthm, grpm, CD4m); proc sort data=&datain; by &idm &grpm; run; proc genmod data=&datain order=freq; class &grpm &monthm &idm; model &CD4m=&monthm &grpm &grpm*&monthm/type3; repeated subject=&idm/ within=&grp type=ar(1) corrw; run; proc genmod data=&datain order=freq; class &grpm &monthm &idm; model &CD4m=&monthm &grpm &grpm*&monthm/type3; repeated subject=&idm/ within=&grp type=IND corrw; run; proc genmod data=&datain order=freq; class &grpm &monthm &idm; model &CD4m=&monthm &grpm &grpm*&monthm/type3; repeated subject=&idm/ within=&grp type=EXCH corrw; run; proc genmod data=&datain order=freq; class &grpm &monthm &idm; model &CD4m=&monthm &grpm &grpm*&monthm/type3; repeated subject=&idm/ within=&grp type=UNSTR corrw; run; %mend exper; %exper(one, id, month, grp, CD4);
When I ran this code, I received these errors:
