Figure 3.

Comparing the SIR dynamics resulting from the average of 100 stochastic realizations of the full spatial model, the spatial model under power-3 closure and the pair equations derived from the mappings for an offset power-law kernel. Parameters as per figure 2 except $\overline{I}(t=0)=0.001$, the basic reproduction number R₀=4 and the infectious period 1/γ=7 days. The pair equations are plotted for the four relevant k values in table 1.
