On autoregressive errors in singular systems of equations


Author Info

Dhrymes (1994, Econometric Theory, 10, 254-285) demonstrates the arising identification and estimation problems in singular equation systems when the error vector obeys an autoregressive scheme, as an extension of restricted least squares. Unfortunately, his main theorem concerning the identification of such systems, does not hold in general, though. Die Identifikations- und Schätzprobleme, die bei singulären System von Regressionsbeziehungen mit autoregressiven Fehlern auftreten, analysiert Dhrymes (1994, Econometric Theory, 10, 254-285) durch eine Erweiterung der restringierten Kleinst-Quadrate-Schätzung. Sein zentrales Theorem zur Identifikation derartiger Systeme gilt jedoch nicht im Allgemeinen.
