Hello.
I am trying to estimate a switching probit using movestay. It converges with
the unweighted data, but it is not correct to use unweighted data. When I
try to do the same with the weighted data, and using different estimation
techniques, either I obtain a non-convergence diagnostic or one of the rho?s
comes out as a 1, which I suppose has the same meaning. 

 I would really appreciate a suggestion on what I should try or look for!
