Fitting error

[Avg12]

Hi,

Starting with a set of data points, I use a fitfun function to fit it to a nonlinear scaling function A^x.
Now, I would like to quantify the error of the fit, to understand how the points deviate from the scaling function.

Can anyone help me with this?
Thanks!

What's the issue with just a brute force least-squares approach?

TTFN (ta ta for now)
I can do absolutely anything. I'm an expert!
