Table 2 Results of the statistical tests comparing b-values and magnitude distributions for positive and negative Coulomb-stress changes, using different slip models and \(\mu {\prime} =0.4\) (same data as previous table). Columns 2 to 4: testing the null hypothesis that there is no difference between the b-values (i.e., b_> = b_<). Both asymptotic normality of the z statistic and a permutation test are used for the calculation of the p-value (labeled as p_norm and p_perm, respectively). In the latter case the number of permutations is 10⁴, and the uncertainty of p_perm corresponds to one standard deviation. Columns 5 to 6: testing the null hypothesis that there is no difference in the distributions, using the 2-sample Kolmogorov-Smirnov test. d_2ks and p_2ks are the 2-sample Kolmogorov-Smirnov statistic and its p-value. Values of ΔAIC = AIC₂ − AIC₁ are also included in the last column.
