WebIn statistics, an augmented Dickey–Fuller test ( ADF) tests the null hypothesis that a unit root is present in a time series sample. The alternative hypothesis is different depending on which version of the test is used, but is usually stationarity or trend-stationarity. It is an augmented version of the Dickey–Fuller test for a larger and ...

WebAug 2, 2015 · 1 Answer. The null hypothesis of the (augmented) Dickey Fuller unit root test is that the series being tested has a unit root (that implies nonstationarity). The basic logic tells you to reject the null … WebNov 2, 2024 · A Dickey-Fuller test is a unit root test that tests the null hypothesis that α=1 in the following model equation. alpha is the coefficient of the first lag on Y. Fundamentally, it has a similar null hypothesis as the unit root test. That is, the coefficient of Y (t-1) is 1, implying the presence of a unit root.
