Estimation of Distribution Algorithms based on Nested Archimedean Copulas [PDF]
AbstractThe main hurdle for EDAs is how to estimate and sample the joint probability distribution, especially in d-dimensiona case (d>2). Copula theory provides a useful tool for multivariate probability analysis, which separates joint probability distribution function into product of marginal distributions.

Modeling the Dependence of Losses of a Financial Portfolio Using Nested Archimedean Copulas [PDF]
In financial analysis, stochastic models are more and more used to estimate potential outcomes in a risky framework. This paper proposes an approach of modeling the dependence of losses on securities, and the potential loss of the portfolio is divided into sectors each including two subsectors.

Densities of nested Archimedean copulas
Nested Archimedean copulas recently gained interest since they generalize the well-known class of Archimedean copulas to allow for partial asymmetry. Sampling algorithms and strategies have been well investigated for nested Archimedean copulas. However, for likelihood based inference it is important to have the density. The present work fills this gap.

Pricing Multi-Event-Triggered Catastrophe Bonds Based on a Copula–POT Model
The constantly expanding losses caused by frequent natural disasters pose many challenges to the traditional catastrophe insurance market. The purpose of this paper is to develop an innovative and systemic trigger mechanism for pricing catastrophic bonds

Assessing the hydrodynamic boundary conditions for risk analyses in coastal areas: a multivariate statistical approach based on Copula functions [PDF]
This paper presents an advanced approach to statistically analyse storm surge events. In former studies the highest water level during a storm surge event usually was the only parameter that was used for the statistical assessment.

Hierarchical Archimedean Copulas for MATLAB and Octave: The HACopula Toolbox
To extend the current implementation of copulas in MATLAB to non-elliptical distributions in arbitrary dimensions enabling for asymmetries in the tails, the toolbox HACopula provides functionality for modeling with hierarchical (or nested) Archimedean ...
