A wavelet network model for nonparametric estimation and economic forecasting 非参数估计的小波网络经济预测模型
Local polynomial estimation method is a kind of a nonparametric estimation methods which are based on data - analytic approaches 局部多项式方法是基于数据来选择模型的一种非参数方法
For many practiced instances , the type of the probability density function is unknown . so density estimation is nonparametric estimation 对于很多实际情况, hmm密度函数所属类型并不知道,此时的密度估计就是典型的非参数估计问题。
At last , combining the related knowledge of wavelet theory and hidden markov models , we introduce wavelet transformation for nonparametric estimation of hmm ' s and discuss how to choose resolving scale of haar - wavelet orthogonal series " estimation 最后,结合小波理论和隐马尔科夫模型的相关知识,将小波变换应用到隐马尔科夫模型非参数估计问题中来,并探讨了其中haar小波正交级数估计量分解尺度的选取。
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。
