New Bivariate Copulas via Lomax Distribution Generated Distortions
AppliedMathWe develop a framework for creating distortion functions that are used to construct new bivariate copulas. It is achieved by transforming non-negative random variables with Lomax-related distributions.

Functionally Constructed Semi Linear Copulas from Fuzzy Implication Operators
AxiomsThis paper proposes a framework for generating symmetric two-branched copulas directly from fuzzy implications via monotone function composition. The proposed approach is based on a two-branched composition principle induced by fuzzy implications and ...

Spatial Tail Dependence and Survival Stability in a Class of Archimedean Copulas
International Journal of Mathematics and Mathematical Sciences, 2016 This paper investigates properties of extensions of tail dependence of Archimax copulas to high dimensional analysis in a spatialized framework. Specifically, we propose a characterization of bivariate margins of spatial Archimax processes while spatial ...

Bounds for Trivariate Copulas with Given Bivariate Marginals
Journal of Inequalities and Applications, 2008 We determine two constructions that, starting with two bivariate copulas, give rise to new bivariate and trivariate copulas, respectively. These constructions are used to determine pointwise upper and lower bounds for the class of all trivariate copulas ...

WORLD FINANCIAL RELATIONS: UNDERSTANDING THE CREDIT DERIVATIVE SWAPS (CDS) DEPENDENCE STRUCTURE
REAdThis study investigates the copula model that best fit to model the dependence structure of Credit Derivative Swaps (CDS) spreads. For the analysis, we consider daily data from the period of January 1, 2009 to December 31, 2014.

Continuous Exchangeable Markov Chains, Idempotent and 1-Dependent Copulas
MathematicsNew copula families are constructed based on orthogonality in L2(0,1). Subclasses of idempotent copulas with square integrable densities are derived.

MODELLING RANDOM COUPLES USING COPULAS MODELADO DE PAREJAS ALEATORIAS USANDO CÓPULAS
Revista Colombiana de Estadística, 2009 Copulas have become a useful tool for the multivariate modelling in both stochastics and statistics. In this article, fundamental properties that allow the characterization of the dependence structure of families of the bivariate distributions defined by
