WebThis paper introduces GARCH-EVT-Copula model and applies it to study the portfolio risk of exchange rates. Multivariate Copulas including Gaussian Copula, t Copula and Clayton Copula were used to describe the structure and extend the analysis from bivariate to any n-dimension. We apply this methodology to study the returns of a portfolio of ... WebThis commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
