Dickey fuller table
WebThe Augmented Dickey-Fuller Test table provides the hypotheses, a test statistic, a p-value, and a recommendation about whether to consider differencing to make the series stationary. The test statistic provides one way to evaluate the null hypothesis. Test statistics that are less than or equal to the critical value provide evidence against ...

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.
