Running PROC GLIMMIX on two different occasions with the same data yield two different estimates for "Fixed Intercept", while eveyrthing else (Covariance estimates/OR/ CL etc.) stayed the same.
This is the second time it happened, the first time was a year ago with a different set of data.
I would really APPRECIATE if someone tells me what is going on.
I assume that you upgraded to a newer version of SAS/STAT between runs?
Hi there!
Thank you so much for your reply! I don't think that I upgraded, but I am running SAS server. Does that automaticlaly upgrade my SAS? Even so why would the estimate varies?
You can find your SAS version by running
%put &=SYSVLONG;
on both systems.
You can get different answers for ill-fitting problems when you change releases or operating systems (Windows <--> Linux). The problem usually indicates that the likelihood function is very flat and/or that the model does not fit the data. For a discussion, see this thread:
THANK YOU SO MUCH! I can't open the thread though, it is invalid.Do you mind providing me the link again? THANK YOU!
I think I had a 'cut-and-paste' error. I have edited and corrected the link in my previous response.
THANK YOU!
