Time Series Forecasting with ARIMA , SARIMA and SARIMAX

WebARIMA is the combination of two models, the auto-regressive and the moving average models. An auto regressive AR (p) component refers to the use of past values in the regression equation for the series Y. The auto-regressive parameter p specifies the number of lags, or past values, to be used in the model. For example, AR (2) is represented as WebWhen fitting an ARIMA model to a set of (non-seasonal) time series data, the following procedure provides a useful general approach.
