The problem is that the initial values that Stata plugs into your likelihood function are not feasible. My hunch is that you'll have to use the -ml- set of commands and program a bivariate probit yourself so as to be able to tweak the algorithm so that (i) it has feasible initial values; and (ii) converges.

I hope this helps,

Marc

Dear statlisters,
I'm estimating several bivariate probit model using the biprobit
command.
In some of them I recieve the follwing error message:

"initial values not feasible"

Does this mean that I can't estimate those models?
Does anybody know how this can be solved?

Thanks,
                        Nestor
