comment Power fit to some experimental data
@ChrisWhite thanks. I did considered them. The absolute value model however assumes the force to be charge independent, which might obscure the case in which the experimental setup it is not that way.

comment Power fit to some experimental data
Thank you so much for this answer. However I think that there is a typo in the definition of $y=f(x)=2x^4$, shouldn't be $y=f(x)=2x^{-4}$. Does non linear least squares manage a set of points with experimental/numerical errors? And also does give the uncertainties in both $a$ and $b$ based on those parameters? Now an introductory bibliographic reference other than wikipedia would be very helpful. Thanks again.

comment Power fit to some experimental data
It would be nice, for the sake of reference and having a concrete example. I'm kind of interested in misuses and misconceptions in the usage of mathematics in the contexts of physics, so thank you.

comment Power fit to some experimental data
Could you please explain the implicit assumption? I don't see it. I don't see neither that the absolute values trick is allowed, but I thought about it.

@Neuneck I also thought about it, taking absolute values, but how may I justify that step? The shifting one is much more obvious but harder to implement.

I was thinking something along this shifting line, I'm editing the question with more info.

comment Higgs mechanism in QED
So I may compute the two products and multiply them. What about commutation issues of derivatives of the components of the perturbation field and the field ?
