Hey Tamas,

Thanks a lot....Your program works so well...one more question for you..where does the program save the results after calculation? Can stata export Latex file after running -margin-? If so,how? I tried outtex after that,but it didnt work....

Once again,thanks!

Lok

The error message is due to the fact that mfx computes derivatives numerically and
for some reasons the computations broke down.

A possible solution is the use of my program -margin- that is faster than mfx.
You can download it using net-aware Stata by typing
