A wavelet network model for nonparametric estimation and economic forecasting 非參數(shù)估計的小波網(wǎng)絡(luò)經(jīng)濟預(yù)測模型
Local polynomial estimation method is a kind of a nonparametric estimation methods which are based on data - analytic approaches 局部多項式方法是基于數(shù)據(jù)來選擇模型的一種非參數(shù)方法
For many practiced instances , the type of the probability density function is unknown . so density estimation is nonparametric estimation 對于很多實際情況, hmm密度函數(shù)所屬類型并不知道,此時的密度估計就是典型的非參數(shù)估計問題。
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,結(jié)合小波理論和隱馬爾科夫模型的相關(guān)知識,將小波變換應(yīng)用到隱馬爾科夫模型非參數(shù)估計問題中來,并探討了其中haar小波正交級數(shù)估計量分解尺度的選取。
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?yún)?shù)估計常用的辦法之一? ?最小二乘法結(jié)合非參數(shù)權(quán)函數(shù)估計法定義了參數(shù)分量和非參數(shù)分量的估計,這里的權(quán)函數(shù)不是通常所采用的核權(quán)函數(shù)或近鄰權(quán)函數(shù),而是由小波方法所得到的權(quán)函數(shù),我們稱它為小波權(quán)函數(shù)。
