Date: Thu, 31 May 2001 08:30:15 +1000 RE: Slow Gradient Method.Bill Based on the discussions I am a little unsure what the value of the slow gradient method is. I would have thought that analytical derivatives would be more accurate and perhaps more stable than numerical - and therefore I am not sure why a potentially slower and perhaps less reliable method is of interest to us? Could you explain where the numerical method might be valuable? I presume for situations where the model can only be described as ODEs then there might be little choice - but otherwise I can't see the advantage.
