Statistical Analysis

Descriptive Statistics

Metric Value Std Dev
Goals per Game 2.73 0.45
Shots on Target 8.2 2.1
Pass Completion 78.5% 5.3%

Advanced Metrics

We calculate several advanced metrics:

  • xG (Expected Goals): Probability-based goal prediction
  • xA (Expected Assists): Likelihood of pass becoming assist
  • PPDA (Passes Per Defensive Action): Pressing intensity metric

Mathematical Formulas

The expected goals model uses logistic regression:

\[P(goal) = \frac{1}{1 + e^{-(\beta_0 + \beta_1x_1 + ... + \beta_nx_n)}}\]

Where: - \(x_i\) represents feature values (distance, angle, etc.) - \(\beta_i\) represents learned coefficients

Code Snippets

Data Processing Example

import numpy as np
import pandas as pd

def calculate_xg(shot_distance, shot_angle):
    """
    Calculate expected goals based on shot location
    """
    # Simplified xG calculation
    distance_factor = np.exp(-0.1 * shot_distance)
    angle_factor = np.cos(np.radians(shot_angle))

    xg = distance_factor * angle_factor * 0.5
    return min(xg, 1.0)

Interactive Elements

Try It Yourself

Future versions will include interactive calculators and data explorers.
