Mean residual life plot for the |E| that exceed the threshold given by different percentiles between 80th and 99.9th (vertical dashed lines). The panels correspond to different latitudes in the central location in Sweden. Panels a–f: |E| exceedance using declustering method DCM-A. Panels g-l: |E| exceedance using declustering method DCM-B. The red line indicates the linear fit between thresholds P99.5 and P99.9. The normalized root mean square error is included in each panel.
