中文摘要：

考虑响应变量随机缺失下线性模型响应变量均值的估计问题，分别获得了基于完全观测样本数据、线性回归插补后的“完全样本”和逆概率加权插补后的“完全样本”得到的响应变量均值估计，并证明了其渐近正态性．

英文摘要：

The present study considers the linear models with response variable data missing at random and investigates the estimation of the mean of response variables, from which we have obtained asymptotic normality of estimators based on the completely observed pairs, the ＇complete＇ data after linear regression imputation and the ＇complete＇ data after inverse probability weighted imputation.
