Wakeby distribution for representing annual extreme and partial duration rainfall series

摘要

In this study, to measure the upper right tail estimate performances for representing annual extreme and partial duration precipitation series at 31 stations in the northeastern and southeastern United States, the results of five-parameter Wakeby-L moments distribution were compared to those by beta-kappa, and beta-P distributions. The statistics of modified Anderson-Darling and average deviation (AD) and the bootstrap resampling to extrapolate the right tail beyond the data showed that the Wakeby distribution gave mostly better results than beta-kappa and beta-P, and sometimes it produced comparable results to those by beta-kappa and beta-P.
