This function is originally from predict.Arima
in stats
package,
but has a nice output
including 100*(1  α)% confidence interval and a prediction plot. It is
similar to FORECAST statement in PROC ARIMA of SAS.
A matrix with lead
rows and five columns. Each column represents the number
of steps ahead (Lead
), the predicted values (Forecast
), the standard errors
(S.E
) and the 100*(1  α)% lower bound (Lower
) and upper bound
(Upper
) of confidence interval.
