Representation of discrete quasi-copulas through non-square matrices
2008In this paper a matrix representation for discrete quasi-copulas defined on a non-square grid In× Imof [0,1]2with m=kn, k≥1 is given. The special case of irreducible discrete quasi-copulas (those that cannot be expressed as nontrivial convex combination of other ones) is also studied.
