Fig. 1From: Metrics for describing dyadic movement: a reviewExample of Prox for δ=3 (left panel) and Cs (right panel). Circles and squares represent locations of two different individuals. Left panel: The numbers inside as well as the arrows represent the time sequence of both tracks. Grey lines correspond to the distances between simultaneous fixes; their values are shown. At the bottom: a dummy variable indicating if distances are below δ for each pair of simultaneous fixes, then the derived Prox and DO (average of observed distances). Right panel: Grey lines represent the distances of all permuted fixes; DE is their averageBack to article page
