garchFit: Univariate or multivariate GARCH time series fitting Description Estimates the parameters of a univariate ARMA-GARCH/APARCH process, or --- experimentally --- of a multivariate GO-GARCH process model. The latter uses an algorithm based on fastICA (), inspired from Bernhard Pfaff's package gogarch.
