Edgeworth Expansion for the OLS Estimator in a Time Series Regression Model

Econometric Theory, 1985, vol. 1, issue 2, 223-239

Abstract: In this paper we consider the situation in which ordinary least squares (OLS) is used to estimate an ARMA (1,1) model with one exogenous variable. Applying Edgeworth expansion techniques, we examine the misspecification errors and the approximate distributions of the OLS estimator. Extensive numerical studies were performed and selected results are shown graphically. In addition, a technical device is developed to calculate the Edgeworth coefficients.
