Constructing Copulas with Given Diagonal and Opposite Diagonal Sections

Communications in Statistics - Theory and Methods, 2011
A method for constructing copulas with given diagonal and opposite diagonal sections is presented. It makes use of a recently developed method for constructing cross-copulas with given horizontal and vertical sections. Conditions guaranteeing the existence of a cross-copula with the given diagonal and opposite diagonal sections are derived. It is shown

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.

Absolutely Continuous Copulas with Given Diagonal Sections

Communications in Statistics - Theory and Methods, 2008
Necessary and sufficient conditions are given in order to ensure that a function δ:[0, 1] → [0, 1] is the diagonal section of an absolutely continuous copula. Explicit constructions are provided.

COPULAS WITH GIVEN DIAGONAL SECTIONS: NOVEL CONSTRUCTIONS AND APPLICATIONS

International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2007
In this paper, we present some methods for constructing copulas with a given diagonal section that are not necessarily symmetric. An interesting application for the construction of copulas with given tail dependence coefficients is, hence, provided.

ON THE CLASSES OF COPULAS AND QUASI-COPULAS WITH A GIVEN DIAGONAL SECTION

International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2011
Let [Formula: see text] and [Formula: see text] be, respectively, the classes of all copulas and quasi-copulas whose diagonal section is δ. We determine under which conditions on δ we have: (a) both [Formula: see text] and [Formula: see text] consist of a singleton; (b) [Formula: see text]. Moreover, a simple construction of copulas with a given convex

On the Structure of the Classes of Copulas and Quasi-Copulas with a Given Diagonal Section

International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2020
In this paper we provide an alternative proof to that given in Ref. 1 to the fact that the class of multivariate copulas with a given diagonal section δ — denoted by 𝒞δ — is a singleton if, and only if, the unique element of the class is the copula of comonotonicity among random variables.
