LRtest seems to be  not appropriate since Stata ask for "force" 'option.
How to explain it? What kind of alternatives is offered here?
I think a general rule is that, if Stata is reporting Wald chi-squares instead of LR chi-squares, then an LR test is at least questionable. (You'll also generally see Stata reporting log pseudo-likelihood rather than log likelihood.) In such situations, use the -test- command instead.
