中文摘要:
      本文目的是介绍病例对照设计四格表资料的χ2检验、优势比的假设检验和区间估计以及使用SAS与R软件实现的方法。针对病例对照设计的特点,重点介绍优势比的概念、假设检验和区间估计方法。对SAS与R软件计算的结果作出解释,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 χ2 test for the data of four-fold tables collected from the case-control design, the hypothesis test and interval estimation of odds ratio, and the implementation of SAS and R software. In view of the characteristics of case-control design, the concept of odds ratio, hypothesis testing and interval estimation were emphasized. It was given that the interpretation of the results calculated by SAS and R software, as well as the statistical conclusion and professional.
