Web2 nov 2024 · A Dickey-Fuller test is a unit root test that tests the null hypothesis that α=1 in the following model equation. alpha is the coefficient of the first lag on Y. Fundamentally, it has a similar null hypothesis as the unit root test. That is, the coefficient of Y (t-1) is 1, implying the presence of a unit root.

An ARIMA (0, 1, 2) model is a Damped Holt's model. An ARIMA (0, 1, 1) model without constant is a basic exponential smoothing model. [9] An ARIMA (0, 2, 2) model is given by — which is equivalent to Holt's linear method with additive errors, or double exponential smoothing. [9]
