动态生命表寿命数据收集与处理过程中常见问题的探讨

DISCUSSION ON SOME COMMON PROBLEMS IN THE LIFETIME DATACOLLECTING AND DISPOSING PROCESSES FOR CONSTRUCTING COHORT LIFE TABLE

种群动态生命表是研究野生动物存活过程的有用工具 ,而其可靠性则依赖于生命数据收集与处理过程中的正确性。文章就野生动物动态生命表收集和处理过程中常见的右删失数据处理问题、个体死亡时间估计、同生群初始值N0 估计以及早期死亡数据的估算问题提出了一点建议和讨论。

The cohort life table is a convenient format to describe survival course of wildlife population. Its accuracy and reliability depend on the lifetime data collecting and disposing processes. Some commonly encountered problems, such as the right-censored data disposing, the failure time estimating, the initial size of cohort estimating, and the early failure data disposing are proposed and discussed here.
