WebMay 26, 2016 · In Dickey-Fuller Test we describe the Dickey-Fuller test which determines whether an AR (1) process has a unit root, i.e. whether it is stationary. We now extend this test to AR (p) processes. For the AR (1) process we take the first difference to obtain the equivalent form where Δyi = yi – yi-1 and β = φ – 1, and test the hypothesis WebAugmented Dickey-Fuller Test ADFTest (R1, lab, lag, criteria, type, alpha): returns an 8 × 1 range which contains the following values: tau-statistic, tau-critical, yes/no (stationary or not), AIC value, BIC value, # of lags (p), the first-order autoregression coefficient and estimated p-value. where
