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 Webconducted at level for up to 5-lagged periods. The stationarity test will utilize the Augmented Dickey-Fuller (ADF) technique (Dickey and Fuller (1981) which is a generalized auto-regression model formulated in the following regression equation (Dickey and Fuller (1981) k t k t k xi i t i k x i t x, 5 1,, , 1 , κ ϖ + ε = − + ∆ − ∆ ...
