Class "Goestica": GO-GARCH models estimated by fast ICA

Description

This class contains the GoGARCH class and has the mixing matrix A as additional slot.

Objects from the Class

Objects can be created by calls of the form new("Goestmm", ...), or with the function gogarch whereby method = "ica" has been set.
