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.
