IV. Goodness-of-fit
Plots of the cumulative distribution functions for the best-fit distributions (as determined by AICc) suggest little evidence of lack-of-fit (Figs. B 2-6.4, 5, 6, 7 and 8). Similarly, bootstrap goodness-of-fit tests did not show evidence for lack-of-fit (P-values > 0.05, Tables B 2-6.9, 10, 11, 12 and 13), with the exception of the Burr distribution, which frequently showed significant lack-of-fit. In general, the coefficient of variation for the HC05 was below 1 for the competitive distributions.
