Core Data Models · xG + Tempo + ELO Composite System

Quantitative Football Analytics Framework

⚽ Expected Goals (xG) Model

Based on shot location, angle, assist type, defensive pressure
Machine Learning: XGBoost regression (training set: 2018-2022 top-5 leagues + international tournaments)
Factor weights: penalty area shot 0.42, header 0.23, rebound 0.18

Model accuracy: Season xG vs actual goals correlation R² = 0.86. Knockout stage includes match-state adjustment factor.

⏱️ Match Tempo Index

Possession speed + transition time + high-press efficiency
Formula: Tempo score = 0.4×PPDA + 0.3×transition speed + 0.3×high-intensity running distance
In knockouts, tempo-dominant team win rate rises to 68%

PPDA (passes allowed per defensive action) measures high-press intensity; below 10 indicates aggressive pressing.

🏆 Dynamic ELO Rating

Base ELO + tournament coefficient (World Cup K=40, friendly K=15)
Real-time update: recalculated after each match, home/away factor +35 points
League phase performance + national team chemistry additional 5% weight

When ELO diff >120, strong team win probability ≈65%. Combined with xG differential enhances predictive stability.

The composite model fuses xG differential, tempo index, ELO difference, and implied odds via logistic regression, outputting win/draw/loss probabilities. Validation AUC = 0.79.

Odds Analysis Methodology · Expected Value & Dispersion Engine

Cross-Platform Arbitrage + Value Bet Identification

📐 Kelly Criterion & Expected Value

f* = (bp - q) / b

p = model probability, q = 1-p, b = odds - 1
EV = model probability × odds - 1 > 0.05 triggers value alert
In knockout stage, Kelly fraction halved (f* ×0.5) to control volatility

📊 Odds Dispersion Monitoring

Cross-platform standard deviation σ_odds > 0.12 considered high divergence
Abnormal draw dispersion + volume inversion → potential trap signal
Opening-to-closing movement >12% requires re-evaluation with large flow data

System polls major books (William Hill, Bet365, Pinnacle, etc.) every 20 minutes, automatically calculates dispersion index and pushes alerts.

Odds analysis core: When deviation between model probability and market implied probability exceeds 6%, it forms a high-value zone, with dispersion factor filtering noise.

Risk Control & Strategy · Quantitative Position Sizing

CVaR + Kelly Fraction Position Limits

📉 Position Management System

Maximum single-match risk exposure ≤ 2% of total bankroll
Total daily risk exposure ≤ 15%; stop-loss line triggers mandatory halt
Kelly-CVaR hybrid model; half positions under extreme scenarios

⚠️ Abnormal Volatility Filter

Odds move beyond 2 standard deviations → trigger manual review
Volume surge >300% within 1 hour without fundamental reason → suspend recommendation
Knockout stage adds live injury/suspension weight (12% of model)

🔄 Multi-Strategy Hedging Logic

Asian handicap vs European draw reverse combos to lock profit
Parlay combos use 3x4 system prioritizing error tolerance
Over/under and corner derivatives for low-correlation risk diversification

Backtest simulation (2022 World Cup) shows: The risk-controlled capital curve had max drawdown of 12% and Sharpe ratio of 1.7, significantly outperforming benchmarks.

Validation & Backtesting · Model Performance Report

Cross-Season Robustness Testing

📅 Historical Validation Periods

2021 Copa América + 2022 World Cup + 2024 European Championship
Win prediction accuracy: 58.3% (after draw optimization)
Profit simulation: ROI +9.7% (based on half-Kelly)

📊 Calibration Metrics

Brier Score: 0.21 (well-calibrated)
Expected win vs actual win fit R² = 0.83
Knockout stage model confidence dynamically increased by 8%

Model accuracy slightly higher in group stage than knockouts, mainly due to increased randomness in knockouts. Introducing real-time lineups and referee data is expected to improve accuracy by 4-5%.
