按照最接近线性优势等级的顺序对一组动物进行排序的常见做法是，这些动物之间的优势通常是可传递的。对优势关系是随机的群体的分析表明，这种方法有惊人的高概率偶然产生一个明显的线性或接近线性的层次结构。在将传递优势用于排名之前，应该先测试它的存在。这里描述了一种合适的统计检验。机会也可能导致基于其他因素的层级结构的线性外观。
The common practice of ranking a group of animals in the closest possible order to a linear dominance hierarchy assumes that dominance among those animals is generally transitive. Analysis of groups in which dominance relationships are random shows that this method has a surprisingly high probability of producing an apparently linear or near-linear hierarchy by chance. The existence of transitive dominance should be tested before it is used in ranking. A suitable statistical test is described here. Chance may also contribute to the linear appearance of hierarchies based on other factors.
