ARIMA-GARCH forecasting with Python by Thomas Dierckx
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.
