Total positivity and dependence of order statistics
Enrique de Amo, José Juan Quesada-Molina, Manuel Úbeda-Flores
In this comprehensive study, we delve deeply into the concept of multivariate total positivity, defining it in accordance with a direction. We rigorously explore numerous salient p…
Supports of quasi-copulas
Juan Fernández-Sánchez, José Juan Quesada-Molina, Manuel Úbeda-Flores
It is known that for every there is a copula whose support is a self-similar fractal set with Hausdorff -- and box-counting -- dimension . In this paper we provide s…
Modeling directional monotonicity with copulas
Enrique de Amo, David García-Fernández, José Juan Quesada-Molina +1
The purpose of this paper is to characterize the concept of monotonicity according to a direction related to a set of n random variables in terms of its associated n-copula C. We s…
Copulas: compatibility and Fréchet classes
Fabrizio Durante, Erich Peter Klement, José Juan Quesada-Molina
We determine under which conditions three bivariate copulas are compatible, viz. they are the bivariate marginals of the same trivariate copula, and, then, construct the class of t…
