"Residue" in General Polynomial Fit Function

[diarmaede]

Do any of you statistics wonks understand how LabVIEW calculates the "residue" output in the "General Polynomial Fit" function?  How does it relate to the R^2 value on an Excel polynomial trendline.

I've been trying to figure this out for hours, but the LV help files don't seem to have the info I am looking for, and I cannot find a good explanation on line.

Thanks,

I figured it out.  I was looking at the TOTAL error of all elements, rather than the average error.
