that home-field advantage is statistically significant we can compute , where is incomplete gamma function. For example, Newcastle in 2015/2016 English Premier League season recorded better result at home field for 13 opponents, same result with 4 opponents, and worse result for two opponents; therefore and hypothesis about home team advantage can be accepted. This procedure was introduced and applied by Marek and Vávra (2017) on English Premier League seasons 1992/1993 – 2015/2016. Later, the procedure was finalised in Marek and Vávra (2020). Marek and Vávra (2018) described procedure which allows to use observed counts of combined measure of home team advantage (, , and ) in two leagues to be compared by the test for homogeneity of parallel samples (for the test see Rao (2002)). The second proposed approach is based on distance between estimated probability description of home team advantage in two leagues ( ) which can be measured by Jeffrey divergence (a symmetric version of Kullback–Leibler divergence). They tested five top level English football leagues and two top level Spanish leagues between 2007/2008 and 2016/2017 season. The main result is that home team advantage in Spain is stronger. Spanish La Liga has the strongest home team advantage, and English football league two has the lowest home team advantage, among analysed leagues. Comparison of home advantage in 19 European football leagues between the 2007/2008 and 2016/2017 seasons was made in Marek and Vávra (2020). They found that, among the analysed leagues, the Super League Greece had the strongest home advantage and English Football League Two had the lowest home advantage. Gaining or losing home-field advantage During the regular season for a sport, in the interest of fairness, schedulers try to ensure that each team plays an equal number of home and away games. Thus, having home-field advantage for any particular regular-season game is largely due to random chance. (This is only true for fully organized leagues with structured schedules; for a counterexample, college football schedules often have an imbalance in which the most successful and largest teams can negotiate more home appearances than mid-majors, a situation that was also prevalent in the early, disorganized years of the National Football League.) However, in the playoffs, home advantage is usually given to the team with the higher seed (which may or may not have the better record), as is case in the NFL, MLB, and Stanley Cup playoffs.
