Temporal changes in dominance networks and other behaviour sequences
Temporal changes in dominance networks and other behaviour sequences
Dominance interactions can be viewed as social networks with directed edges. Only one of the current leading algorithms for ranking individuals (Elo rating) is sensitive to the order in which contests occur; it rewards wins occurring later than losses. The I&SI method of de Vries (1998), while insensitive to contest order, provides a useful alternative in certain contexts. Sequential analysis of the contest matrix (a raw matrix of win–loss contests) can reveal aspects of how quickly relations stabilize temporal changes in win–loss ratios, and the changing roles of individuals. Sequential analysis of the 1/0 outcome matrix (dominant–subordinate relations) can be combined with multiple ranking algorithms and node-based metrics (e.g. hub and authority scores) to provide visually and quantitatively informative assessments of the changing network roles of individuals in the hierarchy.
