“…Because the distribution of Cn depends heavily on K, extensive simulations would be required to establish the distribution of the corresponding ·tatistic, C~) say, for detection of t outliers. However, the extension of En to E~>' say, is feasible from the point of view of tabulating the distribution, because the distribution of the random variable [(n-t-l)/t](t+R n _ t-R.)/(n-t-R n _ t ) is well-approximated by that of an F-variate with 2t and 2(n-t -1) degrees of freedom (Fisher and Willcox, 1978)providing K> 2·5 and n is not too small. As a rough guide to the significance of a given value e, of E~), one might use the first-order Bonferroni bound P(E~» et):::;;(~) P(F2t.2(n-t-1» e.), Some upper critical values of E~), t = 2,3, for selected sample sizes, have also been obtained by simulation (in the manner described in Section 2), using K = 100.…”
