Further Models for Estimating Correlation in Discrete Data
G. M. Tallis · Journal of the Royal Statistical Society Series B (Statistical Methodology) · 1964
Summary This note considers the distribution of the sum of n identically distributed multinomial variates Xi, the correlation coefficient for Xi and Xj being ρ for all i, j, i ≠ j. The initial model, with n and p' = (p1, p2,…,pk) fixed, is generalized by allowing first n, then p and finally both n and p to be random variables.
