This paper presents new estimator for the symmetric distribution function . it is shown that the estimator performs better than the estimator fn ( x ) in bibliography [ 1 ] 摘要針對未知對稱分布函數(shù)提出新的非參數(shù)估計量,并證明了此估計量一致優(yōu)于文獻[ 1 ]給出的估計量。
Secondly , by characteristic statistic , the probabilistic distribution of silt indexes is roughly learned , then the normal and beta distribution probabilistic models are fitted for generally symmetric distribution indexes , and the beta distribution models for all indexes owing to their good adaptability . after tested , the indexes of cuu and < t > m fitted by the beta models are very good 其次,用特征統(tǒng)計量對粉土工程性質指標的概率分布作了粗略了解后,對大致對稱分布的指標作了正態(tài)分布和beta分布擬合,對不對稱分布的指標作了beta分布擬合,最后得出用beta分布擬合c _ ( uu )和_ ( uu )是較理想的。
In this paper , we use the main results of type 2 vdr to analyze the spherical symmetric distribution . we obtain the two equivalent representations of the spherical symmetric distribution . they are both a product of a positive random variable and a random vector with uniform distribution , and the domain of uniform distribution are both related with sphere 本文將第二類垂直密度表示的主要結論應用于球對稱分布,得到了球對稱分布的兩種等價表示形式,它們都是一個正隨機變量與一個均勻分布向量的乘積的形式,且均勻分布的區(qū)域都與球有關。
