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].
