Abstract
Most of the existing Autoregressive (AR) order selection criteria have very poor performance in the finite sample situation. Two well-known examples of such criteria are the Final Prediction Error (FPE) criterion and the Akaike Information Criterion (AIC). In this paper, the case where the region of support for parameters is the first quadrant Quarter Plane (QP) is considered, and modified versions of the AIC and FPE criteria for two-dimensional (2-D) AR model order selection are proposed for this case. In addition, the Exponentially Embedded Family (EEF) criterion for 2-D AR order selection is derived for this case. Performance of the proposed criteria and the existing criteria is evaluated and compared through numerical simulations. The results of these comparisons prove that the proposed AIC and FPE criteria perform much better than the existing versions of these criteria in the finite sample situation. Furthermore, these comparisons reveal that the proposed AIC criterion outperforms all examined criteria in the finite sample situation.
