Dickey fuller table
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. WebSep 25, 2007 · Then you can test the significance of the coefficient xD.lag(x, -1) by using the appropriate Dickey & Fuller critical values (Table B.6 from Hamilton 1994, released in class). From this starting point, you can add lags by changing L=1 to L=2 or L=3 or L=4 and so on. If wish to exclude the intercept, just substitute int=T by int=F.
