Webb14 dec. 2024 · Phillips and Perron (1988) propose an alternative (nonparametric) method of controlling for serial correlation when testing for a unit root. The PP method estimates the non-augmented DF test equation (42.4) , and modifies the -ratio of the coefficient so that serial correlation does not affect the asymptotic distribution of the test statistic.
