摘要：

Recently, maximum likelihood estimators were derived for frequency domain identification of linear time-invariant models with Gaussian input output uncertainty. This note draws attention to an issue that arises in one of the steps in the optimization of the likelihood function. (C) 2019 Elsevier Ltd. All rights reserved.
