I estimated some ordered logit models and  checked whether the proportional 
odds assumption was violated using the Brant  test. In some cases the omnibus 
Brant test suggests the assumption is violated,  but Brant tests of the 
individual regressors in the same models suggest the  assumption is not violated. 
What should one conclude in this case?  Is it  best to be cautious and use, say, 
generalized ordered logit, or is it reasonable  to stick with the ordered 
logit results?  Thanks in advance for any  advice.
