| Zusammenfassung | In practice, measurement results are sometimes described byan estimate, which is not the best one as defined in the GUM. Such alternative estimates arise when the result of a measurement is not corrected for all systematic effects. No recommendation exists in theGUM for associating an uncertainty with an uncorrected estimate. A common choice in guidelines and in the literature is the uncertainty u(y′) =√u2(y)+(y−y′)2 for an alternative estimate y′. It arises from the expected quadratic loss, on which, also in the GUM, the standard uncertainty u(y), and the best estimate y are based. However, such an uncertainty is not a standard uncertainty and we establish, it may not be used for uncertainty propagation. One consequence is, for example, that pairs (y′,u(y′)) are not to be used in calibration certificates. |
