The formal summary class of GoGARCH objects or objects that
extend this class.
Objects can be created by calls of the form new("Gosum", ...)
or are set by the summary-method.
name:character: the name of the original data object.
method:character: the estimation method.
model:formula: The GARCH model formula for the
component GARCH models.
garchc:list: The elements are matcoef matrices
generated by garchFit for the components.
Zinv:matrix: The inverse of the linear map \(X = Y
Z\).
show-method for objects of class Gosum.
