Compositions of Copulas and Quasi-Copulas

Information Sciences, 2004
The object of the research here reported is the study of compositions of copulas, quasi-copulas and semicopulas by means of a two-place real function. Specifically, let A, B and O be mappings from [0, 1]2 into [0, 1], we characterize the properties of O which ensure O(A,B) is in the same class of A and B.

Discrete quasi-copulas

Insurance: Mathematics and Economics, 2005
The authors extend the theory of quasi-copulas to the bivariate discrete case and study various properties. A method of constructing quasi-copulas in the discrete case is also given. The method is illustrated by examples. A function \(C(x, y)\) is said to be a copula if it satisfies the conditions (a) \(C(0, x)= C(x, 0)= 0\) and \(C(1, x)= C(x, 1)= x\)
