WebDistribution. The null distribution of the Péarson statistic with j rows and k columns is approximated by the chi-square distribution with (k − 1)(j − 1) degrees of freedom. This approximation arises as the true distribution, under the null hypothesis, if the expected value is given by a multinomial distribution.
