摘要
在缺失响应变量的不完全数据下,对非参数回归模型进行研究,利用局部线性回归的方法,给出了回归函数m(x)的估计,并证明了缺失数据下局部线性回归光滑具有渐近正态性和相合性.
The model of nonparametric regression function with missing response data was investigated, a estimation of regression function m(x) was made by using local linear regressive approach, and it was verified that the asymptotic normality and consistency were possessed with locally linear regression smoothing for missing data at random.
