WebThe Dickey–Fuller test involves fitting the model y t= + ˆy t 1 + t+ u t by ordinary least squares (OLS), perhaps setting = 0 or = 0. However, such a regression is likely to be plagued by serial correlation. To control for that, the augmented Dickey–Fuller test instead fits a model of the form y t= + y t 1 + t+ 1 y t 1 + 2 y WebJan 30, 2024 · Dickey-Fuller Test for Stationarity Officially, this is called the ‘augmented Dickey-Fuller test’, but most folks just say ‘Dickey-Fuller’ when talking about it. This is a test that tests the null hypothesis that a unit root is present in time series data.

WebThe standard Dickey–Fuller test is essentially an OLS regression: in the simplest form, of the difference of the series (∆Xt) on the lagged level of the series (Xt−1). The “Augmented" Dickey-Fuller or ADF test adds a number of lagged differences to the specification. The DF-GLS test makes use of generalized
