WebKey results: AICc, BIC, and AIC The ARIMA (0, 1, 2) has the best value of AICc. The ARIMA results that follow are for the ARIMA (0, 1, 2) model. If the model does not fit the data well enough, consider other models with similar performance, such as the ARIMA (1, 1, 2) model and the ARIMA (1, 1, 1) model.
