I am fitting a rational function to some data, in my case x varies over many orders of magnitude, so I used to 'Normalize' option when fitting. There is a normalization mean and std to the x, how do I extract that? There isn't a public method to cfit for this as far as I know.
I have attached the fit function in question. The values I am interest in are:
where x is normalized by mean 6.21e+05 and std 1.65e+06
