For a summary of the LSF method and the rationale for using squares vs

Interesting comments from Wolfram here.
They say that squares of the 'offsets' works better than absolute

I would also remind folks that the RMS value for sine waves gives the
correct power calculations while the average of the absolute value
does not.
