Who is the winner between football and financial performance?
Abstract
Nowadays, larger financial values are involved in high-performance sports. Particularly in football, the values are astonishing. Given this context, an impactful question arises, who wins the sports competitions? Is the performance purely sports? Or is it financial performance? Terms like financial doping, and marketing of goal, among others, appear around the world. Allied with this, everyone tries to see the sport as competition only between athletes, but increasingly the financial departments of teams play a decisive role in championships. Statistical tools can be of great help in trying to elucidate this quandary. This investigation seeks to meet this objective through techniques associated with outliers values. The outlier values are usually distinctive elements in the datasets, values that are excessively extreme in terms of the order of magnitude of the variables under study. The procedures for detecting outliers values are already quite widespread, but studies for multivariate outliers values are not yet fully established. Innovative techniques for this purpose are presented in the literature, in particular, the Data-driven Cluster Analysis Method (DDCAM). This present study uses this methodology to investigate the strong association between financial performance and sports results in high-performance Brazilian football.
