Abstract:
We define discrete copulas on a grid of the unit square and show that with each discrete copula there is associated, in a natural way, a bistochastic matrix. This is used in order to introduce the product of discrete copulas. Discrete copulas of order$n$are the smallest convex set containing the irreducible discrete copulas of order$n$introduced by Mayor .
