The multinomial coefficients have a direct combinatorial interpretation, as the number of ways of depositing n distinct objects into m distinct bins, with k1 objects in the first bin, k2 objects in the second bin, and so on. In statistical mechanics and combinatorics, if one has a number distribution of labels, then the multinomial coefficients naturally arise from the binomial coeff…
Webb3.2 - Sampling Schemes. Generating two-way tables of counts is similar to generating one-way tables of counts but with a higher degree of complexity. The main generating probability mechanisms are Poisson, Binomial, and Multinomial models, but for two-way tables, the margins play a big role.
