Fig. 4.

SEL-based percentiles for 1998. For each display, the Y-axis is 100 × ${\stackrel{‒}{P}}_k$ with its 95% probability interval. The X-axis for the upper left panel is $\widehat{P}$, for the upper right is percentiles based on ρ^pm, for the lower left is percentiles based on the ρ^mle and for the lower right is percentiles based on Z-scores testing ρ_k = 1
