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 properties, shedding light on the nuances that characterize this notion

In this paper, we introduce the concept of monotonicity according to a direction for a set of random variables. This concept extends well-known multivariate dependence notions, such as corner set monotonicity, and can be used to detect dependence in

In this article, we answer positively an open question posed in [G. Mayor, J. Suner, and J. Torrens, “Copula-like operations on finite settings,” IEEE Trans. Fuzzy Syst. , vol. 13, no. 4, pp. 468–477, Aug. 2005] concerning the extensions of dis

In this paper we prove that the set of all irreducible discrete quasi-copulas coincides with the set of all discrete quasi-copulas with minimal range. We also provide answers, throughout some counterexamples, to two questions posed in Aguilo et al. [

We provide sufficient conditions for constructing bivariate copulas with given values in rectangles at the corners of the unit square, and find best-possible bounds for copulas of this type.

Currently the fixed-point iteration method with initial guess m0=0.5 is officially recommended by the CIE MES2 system [CIE 191:2010] in order to compute the adaptation coefficient m and the mesopic luminance L m e s . However, recently, Gao et al. [O

In this paper we study some properties of multivariate lower and upper tail dependence coefficients, and analyze the relationship between pairwise tail independence, mutual tail independence, and extremal independence.

We present a general construction that allows to extend a given subcopula to a copula in such a way that the extension is affine on some specific segments of the copula domain. This construction is hence applied to provide convergence theorems for ap

In this paper, we will review our many meetings with Roger B. Nelsen, from August 1986 to the present day. A commented summary of the main results of Roger B. Nelsen and other colleagues work with the author is presented. Most of the mathematical res
