In the present case, we assume that the upper limit is u = 100%, while the estimation power of the derived model is examined for different values of lower limit in the range 0–95%. One should note that symbol PPTS(l) denotes the peak percent threshold statistics of the top l% data. As is shown in Table 4, PPTS statistics show higher values for higher magnitude flows, indicating higher estimation error.
