The study of the application area of Edgeworth series at finding extended uncertainty of indirect measurement result

This study proposes the method of finding the extended uncertainty under the condition when indirect measurement result is additively related to direct measurement results. Using Edgeworth series, we show that approximation of distributions composition allows obtaining the analytical expression of probability density for the indirectly measured quantity. In addition, we outline the boundaries of the application area of the proposed method. We present the table of coverage factors values in relation to the values of skewness and kurtosis coefficients.
