Goestica-class {gogarch} | R Documentation |
Class "Goestica": GO-GARCH models estimated by fast ICA
Description
This class contains the GoGARCH
class and has the mixing matrix
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.
