Distribution of errors in multiple large-volume observations


The role of the Pearson type VII distribution as modified by H. Jeffreys in a posteriori analyses of high precision measurements in metrology is examined. A modern metrological experiment can be regarded as correctly conducted only if the errors for more than 500 measurements obey a t-distribution with v = 5–9 degrees of freedom or a Pearson type VII distribution with an exponent m = 3–5 under constant measurement conditions.
