Ensemble Prediction: A Balanced Approach
The system combines all five rating methodologies using the following weights:
- ELO: 25%
- Massey: 20%
- Pi: 25%
- Glicko: 15%
- TrueSkill: 15%
This weighted ensemble approach ensures a balanced and accurate prediction, compensating for the individual strengths and limitations of each rating model.
How to Use the System for Match Analysis
1. Understanding the Ratings
For each match, the system generates:
- Win probability for both teams.
- Draw probability assessment.
- Loss probability breakdown.
- Predicted winner based on weighted metrics.
- Most likely match outcome.
Match Analysis Information
- Displays total matches analyzed and matches per team.
- Covers a 12-month analysis period.
- Requires a minimum of three matches for accurate rating calculation.
Technical Details & Data Requirements
To ensure reliability, the system utilizes:
- Data from at least three matches per team.
- Performance statistics from the last 12 months.
- Full match results, including expected goals (xG) when available.
Best Practices for Effective Use
- Analyze all rating systems, not just the ensemble output.
- Look for consistent trends across different models.
- Verify the number of matches analyzed to ensure accuracy.
- Use these predictions as part of a broader betting and analysis strategy.
This advanced rating system offers a data-driven approach to evaluating team performance and predicting match outcomes, ensuring bettors and analysts have the most comprehensive insights possible.
Rating Systems Used
1. ELO Rating System

2. Massey Rating System
- Focuses on overall team strength, factoring in margin of victory.
- Uses a mathematical matrix approach to generate rankings.
- Requires at least three matches for an initial rating.
- Analyzes up to 5,000 recent matches for greater accuracy.
3. Pi Rating System
- Specializes in assessing recent form.
- Incorporates expected goals (xG) to measure attacking and defensive performance.
- Includes a time decay factor, weighting recent performances more heavily.
- Adjusts ratings based on home and away results.
4. Glicko Rating System
- Introduces rating reliability, considering uncertainty in results.
- More conservative in adjusting team ratings over time.
- Especially useful for new teams or inconsistent performers.
