	1	协变量缺失下非线性分位数回归中参数的经验似然推断显示文摘文章考虑协变量缺失下非线性分位数回归中参数部分的经验似然统计推断,提出了加权修正的估计方程,并给出了当缺失机制已知和未知时极大经验似然估计的渐近分布,得到了著名的Horvitz-Thompson现象。	王秀丽张淑霞	2016	统计与决策2016，32，17：	3
	2	Estimation and test of restricted linear EV model with nonignorable missing covariates显示文摘This paper deals with estimation and test procedures for restricted linear errors-invariables(EV) models with nonignorable missing covariates. We develop a restricted weighted corrected least squares(WCLS) estimator based on the propensity score, which is fitted by an exponentially tilted likelihood method. The limiting distributions of the proposed estimators are discussed when tilted parameter is known or unknown. To test the validity of the constraints,we construct two test procedures based on corrected residual sum of squares and empirical likelihood method and derive their asymptotic properties. Numerical studies are conducted to examine the finite sample performance of our proposed methods.
