There is a passage in the reference manual under lrtest that I'm interpreting to mean that by using robust you have relaxed assumptions required for the validity of the LR test.



I estimate an ordered probit model with robust standard errors adjusted
for clustering.
LRtest seems to be not appropriate since Stata ask for "force" 'option.
How to explain it? What kind of alternatives is offered here?

Thanks you very much.
