Dear all,
I am using the nlm(base) function for a simple least squares problem.
The size (order of magnitude) of the minimized function near the final
parameter set is normally about 1e-10. Using the fscale=1e-10 argument in
nlm is inefficient (no minimization is performed, iterations=0 or 1). Nlm
only works when the minimized function is multiplied by 1e10 (without
changing the default fscale).
Why? How should I use the fscale arg?
Thanks!
