DIRECT AUTOREGRESSIVE PREDICTORS FOR MULTISTEP PREDICTION: ORDER SELECTION AND PERFORMANCE RELATIVE TO THE PLUG IN PREDICTORS
@inproceedings{Bhansali1997DIRECTAP, title={DIRECT AUTOREGRESSIVE PREDICTORS FOR MULTISTEP PREDICTION: ORDER SELECTION AND PERFORMANCE RELATIVE TO THE PLUG IN PREDICTORS}, author={Rajendra Bhansali}, year={1997} }
A direct method for multistep prediction of a stationary time series con- sists of fitting a new autoregression for each lead time, h, by a linear regression procedure and to select the order to be fitted from the data. By contrast, a more usual 'plug in' method involves the least-squares fitting of an initial kth order autoregression; the multistep forecasts are then obtained from the model equa- tion, but with the unknown future values replaced by their own forecasts. The asymptotic…

Selecting optimal multistep predictors for autoregressive processes of unknown order
- Computer Science

It is shown that when both plug-in and direct predictors are considered, the optimal multistep prediction results cannot be guaranteed by correctly identifying the underlying model's order, which challenges the traditional model (order) selection criteria.

When are Direct Multi-step and Iterative Forecasts Identical?†
- Mathematics, Environmental Science
- 2015
It is shown here that discrepancies in performance between direct and iterative forecasting arise chiefly from the method of fitting, and is dictated by the nuances of the model's misspecification.
