However, when a team award a small number of points this metric is underestimated, vary expressively, among others fragilities. Thus, our objective was to build a new metric to measure home advantage keeping the positive aspects of the previous one and improving all the listed fragilities. It was proposed the new metric and a test to be used in sportive championships. As the study application, it was used data from Brazilian Championship Series-A (2003-2020). As our main result, the new metric was not negatively correlated to the awarded points. The test of the metric let to verify on which occasion there is enough information to affirm that exists home advantage, avoiding the effects of a small number of awarded points. Based on this, of the 370 participations of 43 teams in 18 editions, one participation presented home disadvantage, 259 presented home advantage and 110 did not present home effect. Besides, the metric permitted to visualize the individual behavior of each team throughout the league.</p> ER -
