Forecasting portfolio-Value-at-Risk with nonparametric lower tail dependence estimates [PDF]
Journal of Banking & Finance, 2015 We propose to forecast the Value-at-Risk of bivariate portfolios using copulas which are calibrated on the basis of nonparametric sample estimates of the coefficient of lower tail dependence. We compare our proposed method to a conventional copula-GARCH model where the parameter of a Clayton copula is estimated via Canonical Maximum-Likelihood.
