常见寿命数据类型及生命表的编制方法

摘要

Life table is a convenient tool for depictong the mortality process of a population.The characteristics of four common types of life data,i.e.complete data,right-censored data,left-censored data,and interval data are introduced.Three methods for constructing life table,i.e.Life Table Method,Product-Limit Estimation,and Turnbull Estimation regarding to these tyes of life data are presented.Comparisons are made on the features of the Life Table Method and the Product-Limit Estimation in life table constructing procedure.A special type of life data,the truncated data,is introduced.%生命表是描述种群死亡过程的有用工具。介绍了4种常见的寿命数据类型：寿终数据、右删失数据、左删失数据和区间型数据特征及其相应的数据分析处理方法即生命表法、乘积限估计和Turbull估计法。对生命表法和乘积限估计法应用上的特点进行了比较，同时还对特殊的寿命数据类型——截断数据做了简要介绍。
