Notes. First, F is the ARDL co-integration test; second, the asymptotic critical value bounds are obtained from Narayan (2005, Appendix: Case II); third, LM is the Lagrange multiplier test for serial correlation with a distribution with only one degree of freedom; forth, HET is the test for heteroskedasticity with a distribution with only one degree of freedom; and finally, ***, **, and * represent the 1%, 5%, and 10% significance level, respectively.
