Chris Ferrall has written a Stata program to calculate
rectangle probabilities under the multivariate normal
distribution which is available off this page:
It should be easy to write a wrapper to do MNP using
this subroutine. But, as per Nick's comments, it is
probably better to turn to a lower level language to
estimate such a computationally demanding model.
