Hi all!

 

I am constructing logistic regression model with random effiect for binary data by GLIMMIX.

At first, I am trying to test significance of  intercept random effect of cluster "fid".

To do this, I think it is convenient to  specify constant term only model with GLIMMIX.

 

Anyone know how I can specify constant term only model in GLIMMIX or any other appropriate way?

 

 

--------------------------------------------------------------------------------

proc glimmix data=logitbank method=quad;
class fid;
model ydat2(event='1') = ????
/dist = binary link=logit ddfm=none solution;
random intercept/ subject=fid;
output out =glmout pred =xbeta pred(ilink) =predprob;
covtest;
run;

---------------------------------------------------------------------------------

 

Thanks,

You can leave it empty if you want only fit a intercept term.

 

model ydat2(event='1') = /dist = binary link=logit ddfm=none solution;

HI Ksharp!

Thank you for your help!

I did not come up with that!

 

As you said, I could fit constant term only.

 

Thank you again!
