  1. This paper studies mainly the theories of the semi - parametric regression model : ( 1 ) under proper conditions, using random weighted way to the estimator of the error density f ( x ) of the semi - parametric regression model, this paper proved the strong and weak consistent and the asymptotic unbiased property of the weighted kernel estimation fn1 ( x ) of the f ( x )

    本文對半參數回歸模型:主要做了以下三個方面的理論研究: ( 1 )將隨機加權法應用到半參數回歸模型的誤差密度f ( x )的估計當中去,在適當的條件下,證明了誤差密度的加權核估計( ? ) _ ( n1 ) ( x )的強相合性、弱相合性及漸近無偏性。
  2. Abstract : the generalized shrunken prediction of finite population is introduced, using generalized shrunken least squares estimator of linear regression models. with respect to prediction mean squared error, a necessary and sufficient condition for superiority of a generalized shrunken prediction over the best linear unbiased prediction is obtained. in the case of linear combination of every unit index, a linear restricting prediction is introduced and then a necessary and sufficient condition for superiority of linear restricting prediction over the best linear unbiased prediction is devived

    文摘:利用線性回歸模型的廣義壓縮最小二乘估計,引入了有限總體的廣義壓縮型預測,在預測均方誤差意義下,得到了廣義壓縮型預測優于最佳線性無偏預測的一個充分必要條件;在只能得到每個個體指標的線性組合時,引入了一種線性約束型預測,並得到了線性約束型預測優于最佳線性無偏預測的一個充分必要條件
  3. Based on wavelet analysis, wls is the best linear unbiased estimator of regression model parameters in the context of l / f noise

    基於小波技術的wls法是具有1 f噪聲的系統回歸模型參數的最佳線性無偏估計。
