Abstract

We survey recent developments on hierarchical copula models and focus on those arising as factor models. We unify the literature by introducing the notion of h-extendibility, a notion that generalizes dimension-extendible models to hierarchical structures. Special attention is devoted to h-extendible Archimedean and h-extendible Marshall-Olkin copulas.
