logLik.varFunc.Rd
This method function extracts the component of a Gaussian
log-likelihood associated with the variance function structure
represented by object
, which is equal to the sum of the
logarithms of the corresponding weights.
# S3 method for class 'varFunc'
logLik(object, data, ...)
an object inheriting from class "varFunc"
,
representing a variance function structure.
this argument is included to make this method function
compatible with other logLik
methods and will be ignored.
some methods for this generic require additional arguments. None are used in this method.
the sum of the logarithms of the weights corresponding to the variance
function structure represented by object
.
