摘要: In the analysis of social dominance in groups animals, linearity has been used by many researchers as main structural characteristic a hierarchy. this paper we propose, alongside linearity, quantitative measure for another property hierarchy, namely its steepness. Steepness hierarchy is defined here absolute slope straight line fitted to normalized David’s scores (calculated on basis dyadic index corrected chance) plotted against subjects’ ranks. This correction chance an improvement earlier proposal de Vries (appendix 2 Vries, Animal Behaviour, 1998, 55, 827–843). addition, present randomization procedure determining statistical significance hierarchy’s steepness, which can be test observed steepness expected under null hypothesis random win chances all pairs individuals. Whereas depends number established binary relationships and degree transitivity these relationships, measures individuals differ from each other winning encounters. Linearity are complementary characterize
