Extended Data Fig. 7: Comparison of the (standardized) moments of the distribution of cluster sizes.

a, Mean \(\left[ {\mu = \left< x_i \right>} \right]\), b, variance \(\left[ {\sigma ^2 = \left< \left( {x_i - \mu } \right)^2 \right>} \right]\), c, skewness \(\left[ {\tilde \mu _3 = \left< \left( {x_i - \mu } \right)^3/\sigma ^3 \right>} \right]\), and d, kurtosis \(\left[ {\tilde \mu _4 = \left< \left( {x_i - \mu } \right)^4/\sigma ^4 \right>} \right]\), where \(x_i\) is the number of cells in the \(i\)^th cluster and < > indicates the average over all clusters in a chamber, for experimental egg chambers (red points) and theoretical predictions given by the Forest Fire model simulations (grey; parameters \(p_{{{\mathrm{i}}}} = 0.0001\), \(p_{{{\mathrm{t}}}} = 0.7\), \(p_{{{\mathrm{r}}}} = 0.158114,p_{{{\mathrm{c}}}} = 0.026\)), averaged over 2,200 simulation runs. Grey error bars indicate standard deviation in simulations.
