OBJECTIVES
This study aimed to determine whether elite cricket umpires' decisions contribute to home advantage via leg-before-wicket decisions.
DESIGN
Leg-before-wicket decisions (n = 4971) from actual elite level cricket matches in Australia between 2009 and 2016 were analysed using a binomial logistic regression to predict the umpires' leg-before-wicket decisions.
METHODS
Regressions were performed to determine whether the batter's team (home or away) influenced the likelihood that the umpire would give them out leg-before-wicket.
RESULTS
We found no evidence of home advantage in umpires' leg-before-wicket decisions. In fact, we found evidence that umpires in some instances disadvantage the home team.
CONCLUSIONS
We suggest that the increased professionalism of sports officials, and the scrutiny they are placed under, may lead umpires to reduce or even overcompensate for any existing biases in their decision making.
目的
本研究旨在确定精英板球裁判员的出局判决是否通过球门线前的判决导致主场优势。
设计
使用二项逻辑回归分析 2009 年至 2016 年澳大利亚实际的精英水平板球比赛中的球门线前判决（n=4971），以预测裁判员的球门线前判决。
方法
进行回归分析以确定击球手的球队（主场或客场）是否影响裁判员判定他们球门线前出局的可能性。
结果
我们没有发现裁判员球门线前判决存在主场优势的证据。事实上，我们有证据表明，裁判员在某些情况下对主队不利。
结论
我们认为，体育官员的专业性提高，以及对他们的严格审查，可能导致裁判员减少甚至过度补偿他们决策中的任何现有偏见。
