摘要
本文采用了Gengsheng和Min(2003)提出的经验似然方法,基于一个新的方程对中值回归模型的参数进行统计推断,数值模拟的结果表明,本文所得到的参数估计结果比Gengsheng和Min(2003)的模拟结果更精确.
In this article,we adopt the Gengsheng and Min's methods and make inference based on a different equation which was proposed by Bang and Tsiatis (2002).The numerical results from a simulation study suggest that our results are even better than the Gengsheng and Min's (2003).
