pnt

Results indicate that the Box-Cox approach provides better normality for data transforms, but in the case of evaluation by the statistical properties of the estimations on quantiles through reverse transform, the PNT is superior to Box-Cox method.

研究表明，Box Cox变换后样本的正态性更优，若以反变换后对水文设计值估计的统计性能评价，则以多项式正态变换的效果更优。
