Titel:
Assessing the VaR of a portfolio using D-vine copula based multivariate GARCH models 
Abstract:
We perform Bayesian joint estimation of a multivariate GARCH model where the dependence structure of the innovations across the univariate time series is given by a D-vine copula. Vine copulas are a flexible concept to extend bivariate copulas to the multivariate case. It is based on the idea that a multivariate copula can be constructed from (conditional) bivariate copulas. In particular it is possible to allow for symmetric dependence between some pairs of margins by using e.g. bivariate S...    »
