Hi all! I know that GSL nonlinear least squares routines try to rescale parameters so they should be approximate the same order of magnitude. In my work typical range of parameter values is 10^-7 -- 10^4 (but oftne only 10^-5 -- 10^2) Is that the extremal case for nonlinear fitting or NLS routines could handle it successfully?
