Ben Dave & all,
I'm a user of ADModel (product of Otter Research) Just a word to say that for maximisation, I always rely on Admodel. It's really fast (amazing when you have an important number of parameters), can be used either as a standalone application or as DLL I do use GAUSS (Aptech), R & Stata for my research.. For optimization, this product deserves your attention.. I'm not aware of ADMB-RE so can tell nothing about it Best regards Naji Nassar Le 13/04/05 21:05, ��dave fournier�� <[EMAIL PROTECTED]> a �crit�: > >> I *think* (but am not sure) that these guys were actually (politely) >> advertising a commercial package that they're developing.
