WebMar 21, 2024 · But including larger lags is generally recommended because ADF equation with low lag order suffers from serial correlation hence may lead to biased results. Cite 1 Recommendation The testing procedure for the ADF test is the same as for the Dickey–Fuller test but it is applied to the model where is a constant, the coefficient on a time trend and the lag order of the autoregressive process. Imposing the constraints and corresponds to modelling a random walk and using the constraint corresponds to modeling a random walk with a drift. Consequently, there are three main version…
