object is a one-sided formula, it is used as the argument to
varFixed
and the resulting object is returned. Else, if
object
inherits from class
varFunc, it is returned
unchanged.
varFunc(object)
varFunc,
representing a variance function structure.
varFunc, representing a variance function
structure.
You can use the functions
varWeights and
coef to extract the weights and coefficients, respectively, from a
varFunc variance function structure. For more details, see the links below for the generic functions
varWeights and
coef.varFunc.
