Class "Goestnls": GO-GARCH models estimated by Non-linear Least-Squares

Share:

Description

This class contains the GoGARCH class and has the outcome of optim as an additional slot.

Objects from the Class

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