Copulas are a powerful tool to model dependence between the components of a random vector. One wellknown class of copulas when working in two dimensions is the FarlieGumbelMorgenstern (FGM) copula since their simple analytic shape enables closedform solutions to many problems in applied probability. However, the classical deﬁnition of highdimensional FGM copula does not enable a straightforward understanding of the eﬀect of the copula parameters on the dependence, nor a geometric…

Risk aggregation with FGM copulas
 Computer Science
 2022
This paper builds on two novel representations of FGM copulas based on symmetric multivariate Bernoulli distributions and order statistics, providing a new perspective on risk aggregation with FGMCopulas and risksharing and capital allocation.
A new method to construct highdimensional copulas with Bernoulli and Coxian2 distributions
 Computer Science
 2022
We propose an approach to construct a new family of generalized FarlieGumbelMorgenstern (GFGM) copulas that naturally scales to high dimensions. A GFGM copula can model moderate positive and…
Collective risk models with FGM dependence
 Economics

Statistical Inference Procedures for Bivariate Archimedean Copulas
 Mathematics
 1993
Abstract A bivariate distribution function H(x, y) with marginals F(x) and G(y) is said to be generated by an Archimedean copula if it can be expressed in the form H(x, y) = ϕ–1[ϕ{F(x)} + ϕ{G(y)}]…
