摘要
在各寿命表间进行累计概率比较时,可能出现一种偏倚。这种偏倚是由于各参比人群的构成不同所致。本文以实例证实了偏倚的存在,并在此基础上提出了校正偏倚的方法。
A bias may arise in comparing the accu mulative probabilities which were calculated by cohort life tables. The cause of bias is the heterogeneity of the populations compared. In this paper, the bias was demonstrated and the method of adjustment was developed with the examples.
