Re: [Gretl-users] Saving ADF Residuals

Hi Henrique, If the test shows that you have a unit root, by definition, the residuals doesn't follow a random walk (white nose) and vice-versa. But if you really want to see the residuals, just run an AR(p) regression, by OLS, where p is the "augmented lag" (w/o truncation), then save the residuals.

I would like to save them to check if they follow a white noise process.
