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.

Quasi-Copulas on Discrete Scales
2006In the paper the structure of quasi-copulas on discrete scales is studied. A special attention is given to the study of quasi-copulas with diagonal section. The cardinality of the set of quasi-copulas on L (n) determined univocally by the corresponding diagonal section is shown to be the Fibonacci number p n.

Abstract We review the notion of a quasi-copula and using quasi-copulas we induce in [0,1] some large families of metrics which show to have some interesting probabilistic interpretations.

Transformations of Copulas and Quasi-Copulas
2004Transformations of aggregation operators preserving the class of copulas and quasi-copulas, respectively, are shown to be concave automorphisms of the unit interval. Attractors of copulas are discussed, special attention being paid to power transformations and the relationship between the corresponding attractors and the so-called maximum attractor ...

Multivariate Archimedean Quasi-Copulas
2002Abstract 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.
