In statistics, the Dickey–Fuller test tests the null hypothesis that a unit root is present in an autoregressive (AR) time series model. The alternative hypothesis is different depending on which version of the test is used, but is usually stationarity or trend-stationarity. The test is named after the statisticians David Dickey … See more A simple AR model is $${\displaystyle y_{t}=\rho y_{t-1}+u_{t}\,}$$ where $${\displaystyle y_{t}}$$ is the variable of interest, $${\displaystyle t}$$ is the time index, See more • Enders, Walter (2010).

When a time series has a unit root, the series is nonstationary and the ordinary least squares (OLS) estimator is not normally distributed. Dickey (1976) and Dickey and Fuller (1979) studied the limiting distribution of the OLS estimator of autoregressive models for time series with a simple unit root.
