Robert P. Parks

Overview

Robert P. Parks is an economist in the Department of Economics at Washington University in St. Louis. He co-authored with Edward Greenberg a short but influential paper proposing a predictive Bayesian approach to model selection and multicollinearity (Greenberg-Parks 1997).

Key Contributions

• Predictive model selection (Greenberg-Parks 1997): generalized variance ratio (GVR) and overlap statistics for comparing Student-t predictive densities under full vs. subset regression models; Bayesian interpretation of multicollinearity via the prediction-point deviation $\Lambda'$.
