weighting function method meaning in Chinese
权函数法
Examples
- Weighted function method for a crack opening displacement of an elliptical crack
椭圆裂纹张开位移权函数法 - The basic idea of the estimate method is , firstly , based on the linear model yi = x ' i + ei , defining the least square estimator n of the linear model for the unkown parametric ; secondly , using the estimator n we " ve got to substitute for in the original semiparametric regression model yi = x ' i + g ( xi ) + ei and using the usual nonparametric weighted function method to define the estimator gn ( - ) for the unknown function g ( ) ; finally , defining the estimator 2 for the unknown variance of errors 2
其估计方法的基本思路是先基于线性模型y _ i = x _ i + e _ i ，定义未知待估参数的估计即此线性模型的最小二乘估计( ? ) _ n ；然后将所得估计( ? ) _ n代入原半参数回归模型中，用一般的非参数权函数方法定义未知函数g ( ? )的估计( - By using the least square method and the weighted function method of nonparametric estimation together , this paper defines the wavelet estimators of and g ( ? ) . but the weighted function here is not in the common weighted functions , which include kernal weighted function and nearest neighbor weighted function . however , it is a kind of weighted function deduced by wavelet method , so we call it wavelet weighted function here
本文采用了半参数估计常用的办法之一? ?最小二乘法结合非参数权函数估计法定义了参数分量和非参数分量的估计，这里的权函数不是通常所采用的核权函数或近邻权函数，而是由小波方法所得到的权函数，我们称它为小波权函数。
