3. Data Cleaning and Processing
Clean the collected data by addressing missing values and outliers.
Ensure the time series data is continuous and sorted according to timestamps.

4. Choose Analytical Methods
Time Series Analysis: Utilize ARIMA or SARIMA models to forecast gold prices.
Regression Analysis: Examine the relationship between prices and potential influencing factors—such as interest rates, inflation, and geopolitical events.
