摘要:
A computer-implemented method for forecasting losses in a financial portfolio includes estimating parameters of an autoregressive-moving-average generalized-autoregressive-conditional-heteroscedastic (ARMA-GARCH) model for each individual asset in a financial portfolio by performing a parallel maximum likelihood estimation, estimating parameters of a copula dependence structure for standardized residuals of the ARMA-GARCH model, and estimating a Value-at-Risk (VaR) for the financial portfolio from the ARMA-GARCH model parameters and the copula dependence structure parameters.
