Abstract

. The k‐dimensional pth‐order autoregressive processes {Yt} that are either stationary or have one unstable or explosive root are considered. The properties of the s‐periods‐ahead predictor Ŷn+s, obtained by replacing the unknown parameters in the expression for the best linear predictor YTn+s by their least‐squares estimators, is shown to be asymptotically equivalent to the optimal predictor except in the explosive case. An expression for the mean squared error of Ŷn+s is derived through terms of order n‐1 for normal stationary processes when the parameters are estimated from the realization to be predicted. In addition, small‐sample properties of Ŷn+s are investigated.
