Class "Goestmm": Go-GARCH models estimated by Methods of Moments

Description

This class contains the GoGARCH class and has the weights vector and the matched orthogonal matrices U as additional slots.

Objects from the Class

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