RE: Hessians of posterior density

From: Justin Wilkins <jwilkins@uctgsh1.uct.ac.za> Subject: RE: [NMusers] Hessians of posterior density Date: 6/30/2003 3:45 AM I had thought about it, but apart from being more correct, how would it affect the error? It's still fixed to zero. Running with the term, but with THETA(4) constrained to be positive, yields practically identical results, except that additive error is microscopically small and positive instead of microscopically small and negative... it doesn't seem to be a necessary part of the model but the model won't run without it. It works when fixed to 1x10-5 but this seems to me to be a bit of a workaround rather than a real solution, and produces no improvement in OBJ. Justin
