st: movestay

[mdeidda@stern.nyu.edu]

I'm using the command movestay in order to estimate an endogeneous 
switching regression. The selection equation divides the sample in 2 
subgroups, respectively with 95% and 5% of total observations. I wonder 
if estimation results are sensitive to the dimension of the subsamples, 
and eventually whether  there  is   some way to  deal with this problem 
in order to obtain better results.
thank you
