The ARIMA (AutoRegressive Integrated Moving Average) model is a popular statistical method used for time series forecasting. It is based on the idea that past values of a time series can be used to predict its future values. The ARIMA model is characterized by three parameters: p, d, and q.
p: The order of the autoregressive (AR) term, which represents the number of lagged values of the time series used as predictors.
d: The degree of differencing required to make the time series stationary. Differencing involves subtracting the previous value from the current value to remove trends and seasonality.
q: The order of the moving average (MA) term, which represents the number of lagged forecast errors used in the model12.
