CHECKERBOARD COPULA DEFINED BY SUMS OF RANDOM VARIABLES

Checkerboard copula defined by sums of random variables

We consider the problem of finding checkerboard copulas for modeling multivariate distributions.A checkerboard copula is a distribution with a corresponding density defined almost everywhere by a step function on an m-uniform subdivision of the unit hyper-cube.We develop optimization procedures for finding copulas defined by multiply-stochastic mat
