摘要:
本文利用密度函数与矩的内在联系,探讨了连续分布密度函数的多项式展开,着重对Gram—Charlier级数有限项展开式的精度进行了分析;提出了非对称分布误差及其合成误差置信系数的一种相当精确的近似算法;给出了求取置信系数的回归方程。
Abstract:
In this paper, the polynomial expansion of continuous distribution density function is discussed on the base of the relationship between density function and moments. It is mainly dealed with the accuracy of finite item expansion of Gram-Charlier series. A rather accurate approximation algorithm of confidence coefficients of asymmetric distribution error and its composite error is put forward. At the same time, the regression equations to acquiring, confidence coefficient are given.
