ARIMA Mоdeling 3а. Using the trend-seаsоnаl mоdel identified as the best in section 1c, take its residuals and iterate to determine the optimal ARMA orders, with a maximum of p = 6 and q = 6.  3b. You will use the training data and iterate to find the optimal ARIMA model, with a maximum of p=8, q=8, and d=1. Evaluate the model using appropriate plots and statistical tests. Additionally, provide commentary on the invertibility within the model You may use root analysis. We recommend setting include.mean = TRUE in the ARIMA function to account for the mean in the model fitting. 3c. Apply the SARIMA(0,1,6)(1,1,1) model with a period of 4 and including drift to the training data. Use the same tests and plots that were applied in the previous question (3b), except for the root analysis. Afterward, provide an explanation of the differences and expected outcomes in the predictions when comparing this model to the one used in 3b. Discuss how the inclusion of seasonal components in the SARIMA model may impact the predictions.
