Multivariate Archimedean Quasi-Copulas

2002
Abstract In this paper we define and study basic properties of multivariate Archimedean quasi-copulas. In particular, we examine properties concerning generators, diagonal sections, permutation symmetry, level sets and order.

OPPOSITE DIAGONAL SECTIONS OF QUASI-COPULAS AND COPULAS

International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2009
In 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.
