Does anyone know if there is a way to get the calculated gradient (or outer
product of the gradient) for each observation used in an ml command? I am
estimating a multivariate fractional response model where the first step is
to estimate a multivariate "probit" for each time period and the second step
is to estimate the final parameters using minimum distance. I need to use
the observation level OPG to estimate the correlation between time periods
in order to create the optimal weighting matrix for the MD estimation. 

Any advice is appreciated.
