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 ...

Communications in Statistics - Theory and Methods, 2008 We present a new way of constructing n-copulas, by scaling and gluing finitely many n-copulas. Gluing for bivariate copulas produces a copula that coincides with the independence copula on some grid of horizontal and vertical sections. Examples illustrate how gluing can be applied to build complicated copulas from simple ones.

OPPOSITE DIAGONAL SECTIONS OF QUASI-COPULAS AND COPULAS
International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2009In this paper, we study opposite diagonal sections of quasi-copulas and copulas. The best-possible upper bound for the set of copulas with a given opposite diagonal section being known, we focus on the best-possible lower bound, which in general is a quasi-copula. Moreover, it exhibits an interesting type of bivariate symmetry called opposite symmetry.

On copulas that generalize semilinear copulas
Kybernetika, 2012Summary: We study a wide class of copulas which generalizes well-known families of copulas, such as the semilinear copulas. We also study corresponding results for the case of quasi-copulas.
