Did Adding Stadium Correction Improve My NPB Baseball Predictions? — A Full Backtest Comparison
📰 Dev.to · YMori
Learn how adding stadium correction to a baseball prediction model affected its performance and what insights can be gained from the results
Action Steps
- Add park factor correction to an existing sports prediction model
- Run a backtest comparison to evaluate the impact of the correction
- Analyze the results to identify areas of improvement
- Compare the mean absolute error (MAE) of wins before and after the correction
- Investigate other metrics that may have improved despite no change in MAE
Who Needs to Know This
Data scientists and analysts working on sports prediction models can benefit from understanding the impact of stadium corrections on their predictions. This knowledge can help them refine their models and improve their accuracy
Key Insight
💡 Adding stadium correction to a sports prediction model may not always improve the mean absolute error of wins, but it can still have a positive impact on other aspects of the model's performance
