Subject: Programming Question : sample size in proc surveyreg
Content-Type: text/plain; charset=ISO-8859-1; format=flowed
Hello,
I ran the following code.
%MACRO ancova1;
%DO J = 1 %to 1 ;
proc surveyreg data = milk&j;
class mgroup;
strata SDMVSTRA;
cluster SDMVPSU;
weight WTINT2YR;
model BMXBMI = milk RIDRETH1 PADcom3 ;
title &&titleanovaA&j;
run;
%END;
%MEND ;
%ancova1;
Here, I want to get the samplesize of Observations used in the
analysis in each milk&j by class (mgroup).
However, I just get the following results which do not contain the
samplesize of Observations used in the analysis by class and only contain
sample size of Observations used in the analysis of milk&j.
How can I get the samplesize of Observations used in the
analysis in each milk&j by class (mgroup)?
Result what I got:
