Visualize the results using graphs and charts to make the data more interpretable. Tools like Matplotlib or Tableau can be used for this purpose.

Examples of Predictive Model Applications

With the processed data, you can apply various predictive models to forecast future price movements. Here are a few examples:

1. Time-Series Forecasting

Using historical price data, you can implement time-series forecasting models such as ARIMA or Exponential Smoothing to predict future prices. These models take into account trends and seasonality in the data.

2. Machine Learning Models

Machine learning algorithms like Random Forest or Gradient Boosting can be trained on historical data to predict future price movements. These models can capture complex relationships in the data that traditional statistical methods may miss.
