Dear Members,
Can anyone please explain how I use the command to retrieve the 
condition of the Hessian matrix after running an mprobit? Stata 
specifies the command this way:
real scalar cond  =  norm(A, p) * norm(A^(-1), p) where p takes on the 
value 0, 1, 2 or missing (.)
to collect the matrix A, I am using e(oim)  is this acceptable?
Could someone please show me an example of code for this command that 
they've actually used?
Thank you.
Best,
T.Nelson
