As a rule, the result values h that enter into the calculation of the guarantee conditions will depend on the measured values x as well as on the auxiliary quantities y. Via the definition equations of the auxiliary quantities , the auxiliary quantities y themselves can be expressed by the measured values, As already discussed in Chapter "Error messages, error analyses, and calculation of the covariances" (cf. equation 23), the following applies:
Thus the procedure suggested in Chapter 6.5 of VDI 2048, Sheet 1 can be transferred to the approaches used here:
wherein due to equation (23)
