• Important coordinates for the Field
  • Bottom left/right corner of the field is located at [-1, 0.42] and [1, 0.42], respectively.
  • Top left/right corner of the field is located at [-1, -0.42] and [1, -0.42], respectively.
  • Left/right goal is located at -1 and 1 X coordinate, respectively. They span between -0.044 and 0.044 in Y coordinates.
• Expected Goals Paper
  • y = 0.377 - 0.159 * (distance) - 0.022 * (angle) + 0.799 * (space)
  • "From this equation it is possible to estimate the probability of a shot scoring, based on its location (quantified by distance in yards and angle in degrees) and by whether or not the person taking the shot had space (quantified by 0 if there was an opponent within one metre, and 1 if not)."
