GLS-detrending and regime-wise stationarity testing in small samples

Author

Listed:
  • Lopez, Claude

Abstract

The proposed version of the DF-GLS test incorporates up to two breaks in the intercept. While the asymptotic properties of the DF-GLS test remain valid, the changes in the intercept have an impact on the small sample properties of the test.
