WebThe Dickey–Fuller test described previously is referred to as the AR(1) process; it can be generalized to the Augmented Dickey–Fuller test, to include the case of a general … WebAs the aim was to test the level stationarity and the trend stationarity, analogous models to the simple ones were chosen (Equations (4) and (5)). The formulation of the null and alternative hypotheses, as well as the process of testing via the t-statistics, stay the same, as in the example of the simple Dickey–Fuller test.
