In 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 … See more The testing procedure for the ADF test is the same as for the Dickey–Fuller test but it is applied to the model where $${\displaystyle \alpha }$$ is a constant, See more • In R, there are various packages supplying implementations of the test.
