• Home Team
• Win Percentage
• Rebounds
• Turnovers
• Plus Minus
• Offensive Rating
• Defensive Rating
• True Shooting Percentage

4. Wait ~1-3 minutes for model to finish scraping stats and predicting outcomes
5. Outcomes are outputted as the percent chance that the home team will defeat the away team

Past Predictions

1. Open makePastPredictions.py

2. Edit the call to makePastPredictions with desired start date, end date, season, start date of the season, and output filenames. NOTE: The start date should be at least three days after the season begins and the end date is non-inclusive.

   

3. Run the program either through the terminal or an IDE
