WebYou can access the DF Test tables given by Hamilton(1994) by clicking HERE. Here the null hypothesis is the presence of unit root. Thus, the augmented Dickey-Fuller statistic is -1.678, and lies inside the acceptance region at 1%, 5%, and 10%, as you can see form the tables. Therefore, we cannot reject the presence of unit root.
