ROC diagram for the evaluation period of Experiment 2. Four earthquakes having 7.5 ≤ Mw < 8.5 that occurred in 1988.0–1995.0 were used in calculating r for each of the 210 models tried. The marker shape denotes the p-value in the learning period. Large red markers are used for learning-period elites (p < 15% and r > 0.5 in the learning period), listed in Tables 3 and 4. The three blue curves are identical to those in Figs. 4 and 6; that is, they correspond to (f, r) that would yield p = 5%, 10%, and 15% if there were eight target earthquakes
