摘要：
We introduce a constructive method, by means of a doubly stochastic measure, to describe all the copulas that, in view of Sklar's Theorem, are able to connect a bivariate distribution to its marginals. We use this to give the lower and upper optimal bounds for all the copulas that extend a given subcopula. (C) 2011 Elsevier B.V. All rights reserved.
