Dear Roberto,

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. The fit is not too bad at the HQC level, but I'm not too sure what the accuracy would look like at the ULOQ.

I agree that R2 can be of use, combined with other criteria. Just don't expect more information from it than it can give.

Regards
Ohlbe
