✦ Synopsis

A new form of prediction error method (PEM) is developed. It is applicable to the case where the model structure of interest can be imbedded in a larger model structure whose estimation is relatively easy. An optimal way of reducing the larger model to the smaller model structure is presented and various interpretations of this reduction are given. The proposed method will have the same asymptotic statistical properties as the standard PEM but it can be implemented by a more efficient algorithm. The properties of the method are illustrated by the means of some simulated examples.
