Vine Copula Specifications for Stationary Multivariate Markov Chains
Journal of Time Series Analysis, 2014Vine copulae provide a graphical framework in which multiple bivariate copulae may be combined in a consistent fashion to yield a more complex multivariate copula. In this article, we discuss the use of vine copulae to build flexible semiparametric models for stationary multivariate higher‐order Markov chains.

Empirical researches in financial literature have shown evidence of a skewness and a time conditioning in the univariate behaviour of stock returns and, overall, in their dependence structure. The inadequacy of the elliptical and, in general, symmetrical multivariate constant model assumptions, when this type of dependence occurs, is an almost stylized

Copulas and vines allow us to model the distribution of multivariate random variables in a flexible way. This article introduces copulas via Sklar's theorem, explains how pair copula constructions are built by decomposing multivariate copula densities, and illustrates vine graphical representations.

Simulating Regular Vine Copulas and Distributions
2019For simulation from a d-dimensional distribution function \(F_{1,..., d}\) with conditional distribution functions \(F_{j|1,\ldots , j-1}(\cdot |x_1,\ldots , x_{j-1})\) and their inverses \(F_{j|1,\dots , j-1}^{-1}(\cdot |x_1,\ldots , x_{j-1})\) for \(j=2,\ldots , d\) we can use iterative inverse probability transformations.
