Misspecification Tests in Econometrics: The Lagrange Multiplier Principle and Other Approaches (Econometric Society Monographs)

By bringing together results from the growing literature in econometrics on misspecification testing, this study provides theoretical analyses and convenient methods for the implementation of tests in applied work. Although the main emphasis is on the Lagrange multiplier principle, several other approaches are discussed and the relationships among different methods are examined. The author reviews general checks of model adequacy that do not involve the formulation of an alternative hypothesis. General and specific tests are discussed in the context of multiple regression models, systems of simultaneous equations, and models with qualitative or limited dependent variables. This wide-ranging but integrated book will be useful to a wide audience of applied and theoretical researchers, graduate students, and professional economists. Misspecification tests play an important role in detecting unreliable and inadequate economic models. This book brings together many results from the growing literature in econometrics on misspecification testing. It provides theoretical analyses and convenient methods for application. The main emphasis is on the Lagrange multiplier principle, which provides considerable unification, although several other approaches are also considered. The author also examines general checks for model adequacy that do not involve formulation of an alternative hypothesis. General and specific tests are discussed in the context of multiple regression models, systems of simultaneous equations, and models with qualitative or limited dependent variables This book brings together many results from the growing literature in econometrics on misspecification testing, providing theoretical analyses and convenient methods for application. The main emphasis is on the Lagrange multiplier principle. Tests for misspecification play an important role in the evaluation of econometric models, and the need for such tests has been stressed by several authors.
