Dear All:

I run a bivariate probit model with cluster option in two 
different programs (STATA and LIMDEP) and their std errors 
are significantly different (some variables are insignificant 
in STATA results but they are significant in LIMDEP 
results).  Iam wondering if anybody know how STATA calculates 
the std errors (covariance matrix). The manual only mentions 
about ML method. As far as I know LIMDEP use FIML method but 
I do not think that it will give so much differences.

Thanks
