Figure 3From: Cooperative social clusters are not destroyed by dispersal in a ciliateQuantification of cell aggregation from point pattern analysis. The pair-correlation function g(d) gives the expected number of points at distance d from an arbitrary point, divided by the intensity λ of the pattern. g(d) > 1 indicates aggregation, g(d) <1 regularity of the pattern at distance d. In this example of the picture displayed in Figure 2, cells are aggregated up to a distance of 14. Dashed lines: 95% confidence envelopes obtained from 19 simulations.Back to article page
