生存分析中乘积限估计的鞅方法

Martingale Method of Product Limit Estimation on Survival Analysis

利用鞅的理论研究了生存分析中的有关问题,证明了在非完整数据情况下生存分析中参数估计的一些性质,结合实际模型,给出了生存函数估计的表达式,并用实例进行了验证,获得了良好结果.

In this paper, survival analysis is discussed by using property martingale, some propertys of parametric estimation are proved on survival analysis of non - completed data. We obtain formulation of survival function estimation by integrating practical model and check it up with specific example.
