A class representing rotated versions of the Gumbel copula family (survival, 90 and 270 degree rotated).
Objects can be created by calls of the form
new("surGumbelCopula", ...)
, new("r90GumbelCopula", ...)
and
new("r270GumbelCopula", ...)
or by the function
surGumbelCopula()
, r90GumbelCopula()
and
r270GumbelCopula()
respectively.
