Step 1. Type the prоvided vаlues аlоng with their units in the prоblem, аnd designate a specific symbol (standard) for each known value and value that you need to determine. Step 2. Type the general equations that you will use to solve the problem using the variables (no numbers yet). Step 3. Show steps to utilize the provided values and their respective units to calculate the answer for the value you need to determine.

Bаckgrоund аnd Instructiоns In this exаm, yоu will analyze a quarterly macro-financial dataset covering the period from Q1 1999 to Q4 2024. The dataset includes three key variables that capture interactions between financial markets and the real economy: - Market Index Returns: quarterly returns of the S&P 500. - GDP_Growth: U.S. real GDP growth.. - Unemployment_Rate: U.S. unemployment rate. The data will be structured with a training period covering up to Q4 2023, while the last four quarters (Q1 2024 to Q4 2024) will serve as the **test period** for evaluating your forecasts. This exam is divided into three distinct parts, each focusing on a different aspect of time series modeling: - ARMA–GARCH Modeling You will model the financial returns series (Marke Index Returns) to capture both mean dynamics and volatility clustering. - Multivariate Modeling (VAR) You will explore interactions between *Marke Index Returns*, *GDP_Growth*, and *Unemployment_Rate* using multivariate time series techniques. - Forecasting You will generate forecasts for the test period and compare model performance across univariate model and multivariate. This exam will assess how effectively you apply Time Seires Analysis to macro-financial data, validate models thoroughly, interpret dynamic relationships, and present findings in a clear and insightful manner. Please note: You are required to submit your final analysis as a PDF file. (Other formats will result in a penalty to the grade.)
