Revision: Variance Inflation in Regression
Variance Inflation Factors (VIFs) are reexamined as conditioning diagnostics for models with intercept, with and without centering regressors to their means as oft debated. Conventional VIFs, both centered and uncentered, are flawed. To rectify matters, two types of orthogonality are noted: vector-space orthogonality and uncorrelated centered regressors.The key to our approach lies in feasible ...
متن کاملExploiting Infinite Variance through Dummy Variables in an AR model
In this paper we consider estimation and unit root testing in AR(1) models with infinite variance innovations. Specifically, we study the asymptotic properties of estimators obtained by dummying out ”large” innovations, i.e. exceeding a given threshold. These estimators reflect the common practice of dealing with large residuals by including impulse dummies in the estimated regression. Iterativ...
متن کاملDummy Endogenous Variables in Nonseparable Models
This paper considers the nonparametric identification and estimation of the average effect of a dummy endogenous variable in nonseparable models. The analysis includes the case of a dummy endogenous variable in a discrete choice model as a special case. This paper establishes conditions under which it is possible to identify and consistently estimate the average effect of the dummy endogenous v...
متن کاملHow Robust Is Linear Regression with Dummy Variables
Researchers in education and the social sciences make extensive use of linear regression models in which the dependent variable is continuous-valued while the explanatory variables are a combination of continuous-valued regressors and dummy variables. The dummies partition the sample into groups, some of which may contain only a few observations. Such groups may easily include enough outliers t...
متن کاملInterpreting Dummy Variables in Semi-logarithmic Regression Models: Exact Distributional Results
Care must be taken when interpreting the coefficients of dummy variables in semi-logarithmic regression models. Existing results in the literature provide the best unbiased estimator of the percentage change in the dependent variable, implied by the coefficient of a dummy variable, and of the variance of this estimator. We extend these results by establishing the exact sampling distribution of ...
