Interesting work. A few points: 1) The article segues from saying "a home team advantage exists", which is provable via score sheets, to "referees are biased against away teams", which is difficult to prove and needs justification. I think the former premise is better 2) It should be easy to add tests for statistical significance. From eyeballing I'm not sure that they're significant 3) Different rules have been implemented that may account for any significant differences, e.g., VAR, new handball rules Other than this finding, I wonder if any other artefacts of no-audiences exist. Such as the average number of goals for away teams, penalty taking accuracy.
