摘要
本文论讨非参数统计学在推求设计洪水中的应用,并建立、推导了包含历史洪水资料的非参数核估计模型,实测资料分析表明,非参数模型具有优良的拟合能力,适用于各种水文资料。统计试验结果也表明其设计洪水估值具有一定的精度。非参数估计为设计洪水提供了一条新的研究途径。
The application of nonparametric statistics in flood frequency analysis in this paper is discussed.The new nonparametric kernel estimation models(are established and developed) when historical floods are available. Real data analysis results show that nonparametric models have excellent fitting ability and are suitable to different hydrological data. Simulation results also show that nonparametric approach is reliable in flood quantile estimation. The nonparametric estimation provides another new tool in flood frequency analysis.
