Is there a way to output the covariance parameter estimates in proc genmod in a similar way to the covtest statment in glimmix? I know I can output the working correlation structure. I prefer the method of moments method over likelihood based techniques for GEEs, hence why I am trying to use genmod.
PROC GLIMMIX data = DATA
class CLUSTER OUTCOME VAR1 VAR2;
model OUTCOME (event='1')= VAR1 VAR2
/ dist=bin link=logit ;
RANDOM _residual_ / SUBJECT=CLUSTER TYPE=cs
covtest '1'/ wald;
RUN;
PROC GENMOD data = DATA
class CLUSTER OUTCOME VAR1 VAR2;
model OUTCOME (event='1')= VAR1 VAR2
/ dist=bin link=logit;
REPEATED SUBJECT=CLUSTER / TYPE=cs corrw ;
RUN;
