Log-Likelihood of an ets object
Returns the log-likelihood of the ets model represented by
object evaluated at the estimated parameters.
## S3 method for class 'ets': logLik(object, ...)
- an object of class
ets, representing an exponential smoothing state space model.
- some methods for this generic require additional arguments. None are used in this method.
- the log-likelihood of the model represented by
objectevaluated at the estimated parameters.
