Table 3 Summary statistics of the distribution of residuals from a 1:1 prediction of frequency of grids in Surprise 7.5 yr after fire carrying a particular species from frequency of grids in London 2005 and 2010 mosaics carrying them. Mean = mean of the residual frequency of grids from the 1:1 prediction. RMSE = root mean square error, or the standard deviation of residuals from the 1:1 prediction. Jarque-Bera (JB) statistic and probability describe significance of deviation from a normal distribution, ns = not significant.
