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.

There are various statistical tests to check stationarity, including the Augmented Dickey-Fuller (ADF) test and the Kwiatkowski-Phillips-Schmidt-Shin (KPSS) test. The ADF test is a widely used test for checking the stationarity of a time series, and it checks for the presence of a unit root in the data.
