The estimation of multivariate GARCH models remains a challenging task, even in modern computer environments. This … manuscript shows how Independent Component Analysis can be used to estimate the Generalized Orthogonal GARCH model in a fraction …

A new model class for univariate asset returns is proposed which involves the use of mixtures of stable Paretian distributions, and readily lends itself to use in a multivariate context for portfolio selection. The model nests numerous ones currently in use, and is shown to outperform all its...

combination of the autoregressive moving average models (ARMA); three different models of the arch family, one symmetric (GARCH …) and two asymmetric (GJR-GARCH and EGARCH); and the extreme value theory (EVT). The ARMA models were initially used to … obtain uncorrelated residuals, which were later used for the analysis of extreme values. The GARCH, EGARCH and GJR-GARCH …

We propose an iterative procedure to efficiently estimate models with complex log-likelihood functions and the number of parameters relative to the observations being potentially high. Given consistent but inefficient estimates of sub-vectors of the parameter vector, the procedure yields...
