This paper is concerned with parametric component and nonparametric component estimators in a semiparametric regression model . this model is more flexible and explantory than traditional linear or nonparametric model 本篇論文主要討論關(guān)于半?yún)?shù)回歸模型的參數(shù)和非參數(shù)的估計(jì)問題,半?yún)?shù)回歸模型是近十幾年發(fā)展起來(lái)的一種統(tǒng)計(jì)模型。
To the nonparametric model , we still obtain the rth - mean and completely consistency which generalize and improve the results in [ 4 ] ; to the linear model , we obtain the rth - mean and completely consistency which is a new result ; k )滿足較一般性的條件下,仍獲得了g 。 )的r階平均相合性和一致平均相合性,推廣和改進(jìn)了tran在文獻(xiàn)的結(jié)果,并在加上適當(dāng)?shù)臈l件,獲得g 。
This paper consists of two parts : in the first part , we will discuss the prob - lem of the pth - mean , complete consistency for the estimators of a nonparamet - ric and linear model with l ~ p - mixingale errors ; in the second part , we will dis - cuss the problem of the rth - mean 、 complete consistency for the estimators of themodels above with weak stationary linear process errors and the uniformly mean consistency . to the nonparametric model y _ ni = g ( x _ ni ) + _ ni , 1 i n , let g _ n ( x ) = w _ ni ( x , w _ n1 , … ? xnn ) y _ ni estimate the unknown function g ( x ) . to the linear model y _ i - x _ i1 1 + … ? + x _ iq ? _ q , we use lse _ nj to estimate the unknown parametric _ j 本篇論文主要是由兩大部分內(nèi)容構(gòu)成:一是關(guān)于誤差是l ~ p ?混合序列的線性回歸模型參數(shù)的最小二乘估計(jì)與非參數(shù)回歸模型未知函數(shù)的權(quán)函數(shù)估計(jì)的p ~ -階平均相合性和完全收斂性問題;另一部分是關(guān)于誤差是弱平穩(wěn)線性過(guò)程的線性模型參數(shù)的最小二乘估計(jì)與非參數(shù)回歸模型未知函數(shù)的權(quán)函數(shù)估計(jì)的r ?階平均相合性和完全收斂性以及權(quán)函數(shù)估計(jì)的一致平均相合性問題。
Nonparametric model is widely used in the practical problems , the reason is that the form of the regression function in the nonparametric model is free , and the limits to the random variate ( x , y ) are fewer . in the past several decades , this model is studied carefully by the researchers of statistics , and many achievements are arrived in both theorial fields and in applicational fields 非參數(shù)回歸模型,由于其回歸函數(shù)的形式可以任意,而且對(duì)隨機(jī)變量( x , y )的分布限制較少,因而在實(shí)際中有著廣泛的應(yīng)用背景。幾十年來(lái),統(tǒng)計(jì)工作者對(duì)這一模型進(jìn)行了深入細(xì)致的研究。無(wú)論在理論上還是應(yīng)用上,都取得了許多優(yōu)秀成果。
