In statistics, the Dickey–Fuller test tests the null hypothesis that a unit root is present in an autoregressive 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 … See more A simple AR(1) 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).
