The paper gives an overview of various methods for identifying dynamic errors-in-variables systems. Several approaches are classi2ed by how the original information in time-series data of the noisy input and output measurements is condensed before further processing. For some methods, such as instrumental variable estimators, the information is condensed into a nonsymmetric covariance matrix as a 2rst step before further processing. In a second class of methods, where a symmetric covariance… CONTINUE READING
