回歸分析是用來確定隨機(jī)變量之間關(guān)系的一種統(tǒng)計工具。當(dāng)研究者試圖確定隨機(jī)變量之間的因果關(guān)系時會使用回歸模型。為了探討這些問題,研究者將所觀察到的有關(guān)潛在變量的數(shù)據(jù)集合起來,并使用回歸分析來估計解釋變量對因變量的量化效應(yīng)。本文討論了三種不同的回歸模型:非參數(shù)回歸模型、部分線性回歸模型和異方差部分線性回歸模型。本文主要研究非參數(shù)和部分線性回歸模型在相依誤差下的估計量的漸近性質(zhì)?紤]了與上述主題相關(guān)的三個問題。首先,我們研究了固定設(shè)計非參數(shù)回歸模型中相依誤差的影響。在一些寬泛的條件下,我們得到了固定設(shè)計非參數(shù)回歸模型中加權(quán)估計量的完全相合性和漸近正態(tài)性。此外,本文還對估計量的有限樣本行為進(jìn)行了模擬研究,并給出了估計量的實際數(shù)據(jù)應(yīng)用。接下來,我們研究了如下部分線性回歸模型的一致性,Y(j)(xin,tin)=tinβ+g(xin)+e(j)(xin),1≤j≤k,1≤i≤n,基中xin∈Rp,tin∈R是非隨機(jī)的,g(·)是RP中的緊集A上的一個未知連續(xù)函數(shù),e(j)(xin)是零均值的(α,β)混合隨機(jī)誤差,Y(j)(xin,tin)是可以在點xin和點tin處觀測到的隨機(jī)變量n通過使用概率不等...
