Thanks. I'm not sure why my reply hasn't popped up on statlist, but there was a problem with your suggestion. Here's how it went.

. ereturn scalar k_eform = 3
non e-class program may not set e()
r(152);

Do you know whether I can declare the likelihood itself to be e-class?.. Whether there is some way to call ml maximize as e-class? Perhaps the only way around this is to write a calling routine that calls my likelihood.

Thanks

Paul

So, I have a multi-equation likelihood, and I want to apply eform to all
of the equations. Stata, by default, applies it only to the first. The
help tells you that there is a way to do it, by changing the value of a
scalar e(k_eform) to 3, but they stop short of actually telling you how
to create or alter e(k_eform).
within your estimation program after you've called -ml maximize-, you should add a line:
ereturn scalar k_eform = 3

hope this helps,
Maarten
