WebAs empirically shown below, using a trend variable in ARIMAX negated the need for differencing and makes the series trend stationary. Here is the logic I used to verify. Simulated an AR process. Added a deterministic trend. Using ARIMAX modeled with trend as exogenous variable the above series without differencing.

Web22 ago 2024 · Selva Prabhakaran. Using ARIMA model, you can forecast a time series using the series past values. In this post, we build an optimal ARIMA model from scratch and extend it to Seasonal ARIMA (SARIMA) and SARIMAX models. You will also see how to build autoarima models in python.
