| 本文目的是介绍“分层人-时间资料”率比分析方法与SAS实现方法，具体内容包括以下四个方面：①分层人-时间资料中第i层率比的点估计和置信区间估计；②不同层间率比的齐性检验；③合并率比的点估计与置信区间估计；④分层人-时间资料中发病密度的线性趋势检验。通过两个实例，展示基于SAS软件实现前述四个分析内容的统计计算过程，包括提供SAS程序代码、对SAS输出结果进行解释，并给出统计结论和专业结论。 |
| 英文摘要: |
| The purpose of this paper was to introduce the methods of the "layered person-time data" rate ratio analysis and the SAS implementation. The specific contents included the following four aspects： ① the point estimation and the confidence interval estimation of the layer i rate ratio in the stratified person-time data； ② the homogeneity test of the rate ratios among the different layers； ③ the point estimation and the confidence interval estimation of the common rate ratio； ④ the linear trend test of the incidence density in the stratified person-time data. Through two examples， it showed the statistical calculation process based on the SAS software to realize the aforementioned four kinds of the analysis contents， including providing the SAS program code， the explanation of the SAS output results， and giving the statistical and professional conclusions. |
