FIGURE 3.
Sensitivity (true-positive rate) plotted against 1 – specificity (false-positive rate) for the 10 trees generated (symbols). Gray circle: tree shown in Figure 1. Also plotted are the average discriminability index (d′, solid line), the 95% CI (short-dash line), the d′ = one line (dash-dot line) and the d′ = 0 line (long-dash line).
