Dear all,

I am working on a maximum likelihood estimation problem and I have come
across the following error:

. ml maximize, iterate(0) technique (bhhh) nonrtolerance

moptimize() is trying to hold too many columns of Xb
r(3000);

I cannot find anything in the stata manual or the web about this error.
I am estimating 22 parameters. Any ideas on how to solve this issue? (I
can provide all my code if this helps in clarifying anything).

Thank you very much.

Best,

Carlotta
