We will cover the case with no structural breaks as well as the case with one … WebThe asymptotic distributions of cointegration tests are approximated using the Gamma distribution. The tests considered are for the I(1), the conditional I(1), as well as the I(2) model.
WebThis estimation method gives rise to residual based tests for cointegration. It was shown by Phillips and Hansen [42] that a modification of the regression estimator, involving a correction using the long-run variance of the process ut,would give useful methods for inference for coefficients of cointegration relations; see also Phillips [41].
