WebThe augmented Dickey-Fuller (or ADF) test is a com-monly used unit-root test. Fitting an (autoregressive) AR(k) model, this test examines the null hypothesis of an (autore-gressive integrated moving average) ARIMA(p, 1,0) process against the stationary ARIMA(p+ 1, 0, 0) alternative. Dickey and Fuller (1979) derived the limiting distribution of ... In statistics, the Dickey–Fuller test tests the null hypothesis that a unit root is present in an autoregressive (AR) time series model.
