Actually, I think that is referring to a different problem with 
-mlogtest-. The command can test a lot of things. In Miranda's case I 
think the problem stems from trying to do likelihood ratio tests when 
she is also using robust standard errors.
Also, since mlogtest is a post-estimation command, it is important to 
show the estimation command that preceded it. I'm assuming it 
included the -robust- or -vce(robust)- option or some other option 
that forces robust standard errors.
