I didn't see your last message earlier.

The main thing would be to verify whether Stata or other packages also have the second (better) minimum.

My impression is that many global optimizers might be to expensive for our kind of applications, but it would be good to eventually have some of them available. zuzun (?) uses a global optimizer written by Robert Kern for function and distribution fitting. What I used several times is to pick several starting values for the standard optimizers and see what the best is that they converge to.

With 10 parameters it might not be cheap to cover a reasonable range of starting values or global optimization.
