WebJul 24, 2024 · ADF test — How to test for stationarity A while back, David Dickey and Wayne Fuller developed a test for stationarity — Dicky-Fuller test. It was improved later and renamed to Augmented Dicky-Fuller test, or ADF test for short. It boils down to a simple hypothesis testing: Null hypothesis (H0) — Time series is not stationary. WebJan 4, 2015 · The testing procedure for the ADF test is the same as for the Dickey–Fuller test but it is applied to the model $$ \Delta y_t = \alpha + \beta t + \gamma y_{t-1} + \delta_1 \Delta y_{t-1} + \cdots + \delta_{p-1} \Delta y_{t-p+1} + \varepsilon_t $$ As you very well note, there are variations of the test, which involve restricting $\alpha$ and ...
