...macro-econometrics are linear and/or can contain linear approximations to non-linear relationships, e.g., production functions of the Cobb-Douglas type. Best, Bernhard -----Urspr?ngliche Nachricht----- Von: Berend Hasselman [mailto:bhh at xs4all.nl] Gesendet: Donnerstag, 13.

Can be quite tricky, slow and diverge. You can write your model as a non linear system of equation...
