Data Overview · Multi-Layer Architecture

Covers Matches, Odds, Players, Models
All analysis on this website is built on three data pillars: official match event data (Opta/StatsPerform), live odds aggregation (major bookmakers), and proprietary quantitative factors (xG, Tempo Index, ELO, etc.). The entire pipeline from data collection to cleansing to modeling is automated and updated daily.

Raw Data Layer

  • Match events (shots, passes, fouls, etc.)
  • Team/player basic profiles
  • Real-time odds snapshots
  • Venue/weather/referee history

Derived Metrics Layer

  • xG / xA / possession / shot conversion
  • Tempo Index / PPDA / high-intensity running
  • Dynamic ELO rating / strength differential

Model Output Layer

  • Win/draw/loss probabilities / advancement odds
  • Value betting alerts / hot-cold index
  • Backtesting / Monte Carlo simulations

Derived Data · Proprietary Models & Quantitative Factors

xG / Tempo Index / ELO / Upset Alerts

⚽ Expected Goals (xG) Model

  • XGBoost regression based on 100k+ shot samples
  • Factors: shot distance, angle, assist type, defensive pressure
  • Season xG-actual goals correlation R² = 0.86

⏱️ Tempo Index

  • PPDA + transition speed + high-intensity running
  • Formula: Tempo score = 0.4×PPDA + 0.3×transition speed + 0.3×running distance
  • In knockouts, tempo-dominant side wins 68% of matches

🏆 Dynamic ELO Rating

  • Base ELO 1500, World Cup coefficient K=40
  • Home/away +35 points, tournament coefficient adjustment
  • Updated after every match, margin of error ±12 points
All derived data is built on open-source frameworks; model code is traceable. The xG model training data includes 2018-2024 top leagues + international tournaments, with cross-validation ensuring generalization.

Data Quality Assurance & Update Mechanism

ETL Pipeline · Anomaly Detection · Human Review

🔍 Cleansing & Validation

  • Missing values imputed via KNN / linear interpolation
  • Outliers removed using Z-score >3.0 threshold
  • Cross-source verification (e.g., odds vs market consensus)

⏱️ Update Timing

  • Match data: Real-time push; final version finalized 30 min post-match
  • Odds data: Polled every 15-20 minutes; 5-minute high-frequency pre-match
  • Model predictions: Full update daily at 2 AM + incremental after lineups announced

📋 Audit & Compliance

  • Every data change timestamped (traceable)
  • Simulated data clearly labeled, distinguished from real data
  • Odds data used for strategy research only; not betting advice
Historical data quality report: 2022 World Cup data availability 99.3%, model prediction latency under 3 seconds. All match data sources comply with GDPR and sports data usage regulations.
Note: Data labeled "Simulated" is generated based on historical distributions and quantitative models for analytical demonstration only. Official match data is subject to FIFA and original source releases.
