Unit Root CADF Testing with R

Author

Listed:
  • Lupi, Claudio

Abstract

This paper describes CADFtest, an R package for testing for the presence of a unit root in a time series using the covariate-augmented Dickey-Fuller (CADF) test proposed in Hansen (1995). The procedures presented here are user friendly, allow fully automatic model specification, and allow computation of the asymptotic p values of the test.
