Second-leg home advantage in the Copa Libertadores da América (2005-2015)

ABSTRACT 24. Aims To investigate the home advantage (HA) in the Copa Libertadores da América (CLA) from 2005 to 2015. Methods A naive analysis was applied considering how many times a team that played the second leg at home qualified for the next round. To verify differences between home, away and draw results, the Chi-square ( χ2 ) and the Full Bayesian Significance Test were applied.
