Re: st: Re: optimization problem in Stata?
Yes, matlab is very convinient for such kind of problems.
But I have 3-step-procedure to estimate coefficients. First and third of
which are standard regressions. But second stage is some kind of
non-linear least squares and requires minimazing quadratic form.
