How to account for changes in the size of Sports Leagues? The Iso Competitive Balance Curves.
Résumé
In this note, we focus on the measure of Competitive Balance in sport league when the size of the league varies. We construct a Competitive Balnce index defined as the ratio of the actual standard deviation to the maximal standard deviation, the value of the demoninator depending on the size of the league. On the basis of this ratio we then construct Iso Competitive Balance curves.
