A Characterization of Power Method Transformations through L-Moments

Table 2

L-moment ratios ( 𝜏 ) and their estimates ( 𝑡 ) for the pdf in Figure 1. Each estimate and bootstrap confidence interval (C.I.) was based on resampling 25,000 statistics. Each sample statistic was based on a sample size of 𝑛 = 2 0 0 .
