A Time Series Model with Qualitative Variables

An error occurred while generating the citation.

Abstract

This paper considers a distributed lag model in which the dependent variable is observed qualitatively. The relation of our "lagged index" model to other models that have appeared in the literature is discussed and a computationally tractable method of obtaining consistent estimates is presented. The model is applied to data on party identification in the United States. The results obtained indicate that party identification is responsive to changes in individual opinions, especially regarding the performance of an incumbent president.
