The ranking of sports teams is of significant importance to those who are involved with or interested in the various professional and amateur leagues that exist around the world. We present a ranking algorithm that is simple to implement in SAS code and which gives results that are consistent with some of the best and most well-known computer methods for ranking sports teams. Whether you are tr...

We consider the problem of dynamically rating sports teams based on the categorical outcome of paired comparisons such as win draw and loss in football Our modelling framework is the cumulative link model for ordered response where latent parameters represent the strength of each team A dynamic extension of this model is proposed with close connections to nonparametric smoothing methods As a co...

We present an extensive statistical analysis of the results of all sports competitions in five major sports leagues in England and the United States. We characterize the parity among teams by the variance in the winning fraction from season-end standings data and quantify the predictability of games by the frequency of upsets from game results data. We introduce a novel mathematical model in wh...
