Primacy and ranking of UEFA soccer teams from biasing organization rules

摘要: A question is raised on whether some implied regularity or structure, as found in the soccer team ranking by Union of European Football Associations (UEFA), due to an implicit game result value score competition conditions. The analysis based considerations complex systems, i.e. finding power other simple law fits are appropriate describe internal dynamics. It observed that specifically organized: a major class comprising few teams emerges after each season. Other classes, which apparently have regular sizes, occur subsequently. Thus, notion Sheppard primacy index envisaged findings. Additional indices discussed for enhancing features. These measures can be used sort out peer classes more general terms. very simplified toy model containing components UEFA rules suggests such extrinsic property ranking, obtained many nonlinear systems under boundary condition constraints.
