WebNotes and Sources: Standard Dickey-Fuller and Phillips Perron unit-root tests are ap-plied to the regression residuals using the critical values above instead of those on the previous page, focussing entirely on the coe–cients of the laggeed residual. Except for the case of 6 variables, these critical values were calculated using Monte Carlo ...

In statistics, the Dickey–Fuller test tests the null hypothesis that a unit root is present in an autoregressive time series model. The alternative hypothesis is different depending on which version of the test is used, but is usually stationarity or trend-stationarity.
