摘 要:
半变系数模型在统计建模中具有重要的应用.最近几年,人们提出了许多方法来估计其常系数和函数系数,但是估计的渐近性质还没有被系统的研究.本文介绍了半变系数模型的PLS估计,在Fan和Huang对常系数渐近性质研究的基础上,给出了函数系数的渐近正态性。[著者文摘]

Abstract:
In this paper,the profile least squares estimation is introduced. Based on the ideals of Fan and Huang(2005),in which the asymptotic normality of parametric component in semivarying coeffcients model has been shown, the asymptotic normality of nonparametric component in semivarying coeffcients model is investigated.[著者文摘]
