WebAug 29, 2024 · It can be easily understood via an example with an ARIMA (0, 1, 0) model (no autoregressive nor moving-average terms, modeled using first-degree difference) involved: Without parameter: the model is xₜ = xₜ₋₁ + εₜ, which is a random walk. With parameter: the model is xₜ = c+ xₜ₋₁ + εₜ. This is a random walk with drift. WebA logical value indicates whether to show legend or not.
