欧洲足球协会联盟足球队排名的内在类别

Intrinsic Classes in the Union of European Football Associations Soccer Team Ranking

Marcel Ausloos

摘要:

欧洲足球协会联盟(UEFA)在2009-2014年期间对足球队进行了排名,发现了很强的结构规律性。根据5个赛季的比赛,它涉及424到453支球队。分析是基于排名大小理论的考虑,大小是在赛季结束时的欧足联系数。出现三类:(i)少数“顶级”团队,(ii)300个团队,(iii)分布尾部的其余参与团队(约150个)。有明显的经验法则描述每一个类。一个三参数的Lavalette函数被用来描述凹曲线随着秩的增加,并区分尾部从中心的行为。

英文摘要:

A strong structural regularity of classes is found in soccer teams ranked by the Union of European Football Associations (UEFA) for the time interval 2009-2014. It concerns 424 to 453 teams according to the 5 competition seasons. The analysis is based on the rank-size theory considerations, the size being the UEFA coefficient at the end of a season. Three classes emerge: (i) the few "top" teams, (ii) 300 teams, (iii) the rest of the involved teams (about 150) in the tail of the distribution. There are marked empirical laws describing each class. A 3-parameter Lavalette function is used to describe the concave curving as the rank increases, and to distinguish the the tail from the central behavior.
