The new definition leads to modifications in the treatment of calibration data. It is now necessary to establish a relation which allows obtaining any measurement result from any indication of the measuring instrument. This relation takes into account uncertainties and any covariances, both on the values of the standards used and on the indications and maybe even the covariances. The usual statistical technique of regression, the ordinary least squares adjustment, does not generally enable to reach this goal. As a result, more sophisticated methods need to be used, for instance the Generalised Gauss Markov Regression. We compared both methods on a gas chromatograph calibration example.
