Model Selection In Factor-augmented Regressions With Estimated Factors

No 1391, Working Paper from Economics Department, Queen's University

Abstract: This paper proposes two consistent in-sample model selection procedures for factor-augmented regressions in finite samples. We first demonstrate that the usual cross-validation is inconsistent, but that a generalization, leave-d-out cross-validation, selects the smallest basis for the space spanned by the true latent factors. The second proposed criterion is a generalization of the bootstrap approximation of the squared error of prediction from Shao (1996) to factor-augmented regressions. We show that these procedures are consistent model selection approaches. Simulation evidence documents improvements in the probability of selecting the smallest set of estimated factors than the usually available methods. An illustrative empirical application that analyzes the relationship between stock market excess returns and factors extracted from a large panel of U.S. macroeconomic and financial data is conducted. Our new procedures select factors that correlate heavily with interest rate spreads and with the Fama−French factors. These factors have in-sample predictive power for excess returns.
