چکیده

Vine copula models have proven themselves as a very flexible class of multivariate copula models with regard to symmetry and tail dependence for pairs of variables. The full specification of a vine model requires the choice of vine tree structure, copula families for each pair copula term and their corresponding parameters. In this survey we discuss the different approaches, both frequentist as well as Bayesian, for these model choices so far and point to open problems.

Truncation of vine copulas using fit indices

Vine copulas are flexible multivariate dependence models, which are built up from a set of bivariate copulas in different hierarchical levels. However, vine copulas have a computational complexity that is increasing quadratically in the number of variables. This complexity can be reduced by focusing on the sub-class of truncated vine copulas, which use only a limited number of hierarchical leve...

Bayesian Model Selection of Regular Vine Copulas

Regular vine copulas are a novel and very flexible class of dependence models. This paper presents a reversible jump MCMC strategy for Bayesian model selection and inference of regular vine copulas, which can select all levels of a regular vine copula simultaneously. This is a substantial improvement over existing frequentist and Bayesian strategies, which can only select in a sequential, level...

Model selection for discrete regular vine copulas

Abstract Discrete vine copulas, introduced by Panagiotelis et al. (2012), provide a flexible modeling framework for high-dimensional data and have significant computational advantages over competing methods. A vine-based multivariate probability mass function is constructed from bivariate copula building blocks and univariate marginal distributions. However, even for a moderate number of variab...

Bayesian model selection for D-vine pair-copula constructions

In recent years analyses of dependence structures using copulas have become more popular than the standard correlation analysis. Starting from Aas, Czado, Frigessi, and Bakken (2009) regular vine pair-copula constructions (PCCs) are considered the most flexible class of multivariate copulas. PCCs are involved objects but (conditional) independence present in data can simplify and reduce them si...

A Study Of The Vine Set

In this paper we establish the convergence of the vine copulas estimator and prove that all vine copula estimator have comparable asymptotic variance. We make these proofs under weaker hypothesis than that of the framework usually considered in the literature. Namely, we lift the conditional independence hypothesis through the use of conditional copulas. We also exhibit the underlying tree stru...
