varComb
class,
representing a combination of variance functions. The corresponding
variance function is equal to the product of the variance functions of
the
varFunc
objects listed in
...
.
varComb(...)
varFunc
representing
variance function structures.
varComb
object representing a combination of variance
functions, also inheriting from class
varFunc
.
You can use the functions
varWeights.varComb
and
coef.varComb
to extract the weights and coefficients, respectively, from the variance function structure. For more details, see the links below for the generic functions
varWeights
and
coef.varFunc
.
