How relevant is the grading of soccer matches by experts and algorithms? An objective view — •Andreas Heuer1 and Jens Smiatek2 — 1Institute for Physical Chemistry, University of Münster, Germany — 2Institute for Computational Physics, University of Stuttgart, Germany
The grading of soccer players, e.g., by sports magazines is common usage to evaluate their performance. Often these grades are important parameters for player transfers and internet manager games.
In this talk we answer the question about the quality of the grades on a team level. We analyze grades, formulated by experts, and grades, determined on an algorithmic basis using match-data.
Via a specifically designed statistical analysis we can identify on an objective basis to which degree the grades indeed reflect the strengths of the individual teams or whether they are just a mirror-image of the random effects, inherently present in soccer matches or follow from the prejudices of experts. Interestingly, it turns out that the quality of both types of grading systems is relatively poor.
