Abstract :
Let H* be the transfer function of a linear stochastic system such that H* and its inverse are in H∞( D). Writing the system as an AR(∞) system, the best AR( k) approximation of the system is estimated using the method of least squares. Then the effect of undermodeling and parameter uncertainty (due to estimation) on prediction, and the optimal choice of k are investigated. The result is applied to the AR approximation of ARMA-systems
