  did you try the maximize options for sureg? You can have try several things from the manual, eg add the difficult option, for instance or change the tolerance criteria.  You may as well try to specify a different maximisation algorithm or switch between maximisation algorithms. It usually works. See help maximize for these options.

Hope that helps

Hi all

I have a sets of mixed cross country data started from 1996 to 2000 and
trying to estimate SUREG model. My equations system consists of three model
and when I invoking 'isure' option, the stata output show " convergence not

Is it valid to report the output since the data failed to converge?
