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).

WebTo test H0, Dickey and Fuller (1979) proposed the studentized statistic tn = ρˆn −1 Stdd(ρbn), (1.4) where Stdd(ρbn) denotes an estimator of the standard deviation of the OLS estimator ρbn. The asymptotic distribution of tn under H0 is non-standard and is well known in the literature. WebDickey-Fuller test (ADF). his test is a part of the methodology implemented by Dickey and Fuller (1979, p. 430) as a way of testing stationarity in time series. According to Campbell and Lo (1997), unit root test is constructed in a way that the null hypothesis expects time series to be stationary at irst diference, while the alternative hypothesis phoenix the bird
