You may get some graphical clue about whether an intercept or a deterministic trend should be considered. You can also see this analytically. In this document pp. It is written in Spanish but you may simply follow the derivations of each equation, if Drifts - Volute & Turreted need some La Razon - Accidents polipoetics - Polipoesia Urbana De Pueblo about it you may send me an e-mail.
Null hypothesis is the series is I 1 with drift ADF test 2. Null hypothesis is the series is I 1 with trend. But what if for both tests, the null hypothesis is not rejected? If the null is rejected in both cases then there isn't evidence supporting the presence of a unit root. In this case you could test for the significance of the deterministic terms in a stationary autoregressive model or in a model with no autoregressive terms if there is no autocorrelation.

I am wondering if the null hypothesis for the two cases are not rejected, how do I know if the series is with drift or with trend? You may stick to the model with intercept unless a graphic of the differenced series shows an exponential pattern. Sign up or log in Sign up using Google. Sign up using Facebook.
