摘要
借助于样条技术 ,给出了利用先验信息对初始估计进行修正的新方法 .这些先验信息可以包含数据的凸性以及增减性 .同时讨论了这种数据处理方法在生存分析尤其是精算等领域中的应用 .
This paper presents a new revision method towards the initial estimate sequence in accordance with the prior opinions by means of the technique of spline.These prior opinions include the convexity as well as the monotony of the data,meawhile,some significant applications in survival analysis especially in the field of actuarial science are discussed.
