‘The moments of the Pearson chi-squared statistic and the minimum expected value In two-way tables’

Abstract

On page 518 the expressions for u 2 and v 2 should be u 2 = ∑ s i − 2 − ( n 3 / N 2 ) , v 2 = ∑ t j − 2 − ( m 3 / N 2 ) In view of the complexity of the formula (3·1), it is worth noting that it gives the same numerical results, in a number of examples, as the subsequent formula of Mielke & Berry (1985). It also agrees numerically in these examples with the exact third central moment calculated using the enumeration algorithm of Saunders referred to in our paper.
