st: how to generate Hessian matrix in STATA?

Teresa Linz
HI,

I am estimating a cost funtion with seemingly unrelated
regression. Hence I estimate the cost function and four
share equations jointly. I now want to test the concavity
of my cost function. Is there an easy way to
produce the eigenvalues of the Hessian matrix in STATA?
You really would help me a lot with a short answer.
thanks,
Teresa
