In this paper, we present the concept of being monotonic in sequence according to a specific direction for a collection of random variables. This concept broadens the existing notions of multivariate dependence, such as sequential left-tail and right

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
