".The function summary
is used to obtain and print a summary of the
results, while the function plot
produces a plot of the forecasts and prediction intervals.
The generic accessor functions fitted.values
and residuals
extract useful features of
the value returned by ets
and associated functions.
An object of class "forecast"
is a list containing at least the following elements:
