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. |
