This paper analyzes the covariance of the estimated system matrices in PO-MOESP method and applies the result to the calculation of the covariance of the coefficient of the transfer function obtained from the estimated system matrices. In the analysis of the covariance of the system matrices, consistent estimates of Kalman gain and the covariance of the innovations process are utilized. Unscented transformation is applied to calculate the covariance of the coefficient of the transfer function. A numerical simulation is shown to illustrate the validity of the analysis.
