I've had occasion to use the MLE routine to run some simple Probit
analyses. I was going to work with some bivariate Probit models, but am
I correct in my belief that Gretl doesn't have a bivariate normal cdf?
FYI. The biggest problems I had were moving between matrices and
variables, and trying to save variables with fewer than the number in
the initial dataset (other than 1x1).
