Quote: reffy "Moral of the story, teams tend to win more games at home than away and as a consequence most referees will officiate over more home wins than away. Chicken & egg.'"
Not quite. Correlation doesn't equal causation, but if you are correct that most teams tend to win more at home than away, and I'm inclined to think that you are, there are a number of factors that contribute to that, and referee influence
may be one of them. Vbfg's data, however, doesn't quantify that influence or indeed prove its existence.
