摘要

在响应变量随机缺失时,利用拟似然方法给出了广义变系数模型中非参数函数系数的估计.研究了所得到的估计的渐近性质,求出了估计的渐近偏差与渐近方差,并进行模拟比较.

Abstract

A quasi-likelihood estimation is considered for nonparameter coefficient function in generalized varying-coefficient model with response variables missing at random. It is shown that the proposed estimation is asymptotically normal, moreover, the asymptotical bias and the variance of the estimation are given.
