Avaliação esportiva utilizando técnicas multivariadas: construção de indicadores e sistemas online
Resumen
The main objective of this research is to provide statistical tools that allow the comparison
of individuals in a speci ed sports category. Particularly, the present study is focused
on the performance evaluation in football using univariate and multivariate methods. The
univariate approach is given by Z-CELAFISCS methodology, which was developed with
the purpose of identifying talents in the sport. The multivariate approaches are given
by the construction of indicators, speci cally by means of principal component analysis,
factor analysis and copulas. These indicators allows the reduction of the dimensionality
of the data in studying, providing better interpretation of the results and improving comparability
between the performance and assortment of individuals. To facilitate the use
of the methodology studied here was built an online statistical system called i-Sports.
