Pаrt I: ARIMA аnd GARCH Mоdelling (30 pоints) 1а. Plоt both time series and comment on their stationarity properties. Also, explore and comment if there is any correlation between SP and Consumer Price Index and what implications this would have to forecast. 1b. Devide the data in training and testing sets, using the period 1985 to Dec 2022 to train and the last 6 observations for testin, i.e. Jan 2023 to Jun 2023. Using the *SP500*, apply the iterative BIC selection process to find the best, non-trivial ARIMA model order using the max orders (pmax = 6, qmax = 6) and d orders of max 2. Make sure to apply the model fit to the training data. Fit each model, then evaluate the Box-Ljung test, ACF on the model residuals and squared residuals. Note: Use the 'ML' method in the arima() command to ensure convergence. 1c. Using the *CPI* data, apply the first difference, and model the ARMA-GARCH with orders (2, 5) x (1, 1). Evaluate the Box-Ljung test results and the ACF when performed on the model residuals and squared residuals. 1d. Apply the selected model in (1b) and the model from 1c and obtain the rolling forecasts for the 6 months of data for 2023. Visualize the predictions versus the observed data and derive the MAPE for each time series. What can you say about the accuracy of the predictions over the two year period? Note If your model uses the differenced data, you will have to get the actual predictions from your forecast outcome. 1e. Using the final order for your model for SP data (question 1b), estimate a APARCH model, write the model equation and evaluate if there is necessity to control for assymetry in the model. Support your conclusion using the News Impact curve to compare the GARCH model from 1b and the APARCH. Part II: Multivariate Modeling (30 points) 2a. Fit an unrestricted VAR model using the first differenced data. Select the order with the Hannan-Quinn information criterion and maximum order p=15. 2b. For each time series in the VAR model in part (a) using the first data division only, apply the Wald test to identify any lead and lag relationships between the two time series. Use a significance level of
