  • Abstract
    We study the statistical properties of a number of closed-loop identification methods and parameterizations. The focus is on asymptotic variance expressions for these methods and by studying the asymptotic variance for the parameter vector estimates we show that indirect methods fail to give better accuracy than the direct method
