Webb9.2.1.1.2 Augmented Dickey-Fuller (ADF) Test. The Augmented Dickey-Fuller Test (ADF) is a popular unit root test. An R implementation of the test can be found in the library tseries (function adf.test). The null hypothesis is that the series has a unit root, and the alternative hypothesis is that the series is stationary or trend stationary. WebbAutres tests de stationnarité. Il existe deux types de test de stationnarité différents : les tests de stationnarité comme le test KPSS pour lesquels l'hypothèse nulle est que la série est stationnaire et les tests de racine unitaire comme le test de Dickey-Fuller, le test augmenté de Dickey-Fuller ou encore le test de Phillips-Perron pour lesquels l'hypothèse …
