Subject | st: gllamm error "something went wrong in comprob3" |
Date | Fri, 25 Jun 2010 15:50:01 -0400 |
Hello all,I'm using the gllamm function to do a multilevel logistic regression with survey weights.
I am getting an error message and am not sure what could be going wrong - it tells me that "can't get correct log-likelihood: -241633.32 should be -241586.39
something went wrong in comprob3"Below is the output. Anyone have any thoughts as to what's going on and how to fix it?
