使用矩比图的172个澳大利亚流的峰值年流量的分析表明，日志皮尔逊III型分布是适当的极端洪水流量的估计。将峰值流量曲线的偏度系数设置为零的做法受到质疑，因为这些偏度系数在统计上与零没有差异。
An analysis using moment ratio diagrams of peak annual discharges of 172 Australian streams suggests that the log Pearson Type III distribution is appropriate for estimation of extreme flood discharges. The practice of setting to zero the coefficients of skewness of the logarithms of the peak discharges that are not statistically different from zero is questioned.
