Arguments are presented that show that it is ineffective to replace distribution propagation by uncertainty propagation in estimating the uncertainty of measurements, which has a bearing on the accuracy and difficulty of estimating indirect-measurement uncertainties with nonlinear transformations from input data. __________ Translated from Izmeritel’naya Tekhnika, No. 2, pp. 15–18, February, 2008.
