Jacobian J: new section

Can anyone provide a section or information comparing the LMA with other algorithms such as the Conjugate-Gradient method?[[User:Mxbuck|MxBuck]] ([[User talk:Mxbuck|talk]]) 19:18, 23 September 2009 (UTC)

I think there's a little mistake in the definition of J:
 
Shouldn't it be: J = S(β) / dβ ?
 
This would also correspond to this (from the external links):

We're trying to minimize the error, so taking the Jacobian of the original function wouldn't make sense.
