❝ I have here very nice examples of linear calibrations with 1/x2 weighting, with R2 > 0.99, where visually I would say that a quadratic fit would be much more appropriate than linear. […]



Tanks Ohlbe for your replay,
It would be interesting to have one of your example, in order to better understand.
Did you try to calculate the quadratic fit that you "felt" better represented with the data and which R-square did you obtained?

Thanks a lot
Roberto

in which he must be an expert in order to compete with other people.
