It analyzes the extent to which restricting attention to processes with rational spectral density matrices reduces the number of observationally equivalent models. It focuses on rational specifications of spectral density matrices since rational parameterizations are commonly employed in the analysis of the time series data."^^; "1981-09"; "2019-10-21T19:16:09.357206339+00:00"^^; "https://doi.org/10.21034/sr.72"; ; "https://creativecommons.org/licenses/by-nc/4.0/"; "Thu Nov 7 22:22:26 2019"; "https://creativecommons.org/licenses/by-nc/4.0/"; "Research Paper"; "692", "316"; "Staff report (Federal Reserve Bank of Minneapolis.
