| 本文目的是介绍配对设计四格表资料的McNemar?s χ2检验及SAS和R软件实现。首先，提出配对设计四格表资料存在3种情形，即①特设“金标准”的配对设计四格表资料，值得进行统计分析；②缺乏“金标准”的配对设计四格表资料，不值得进行统计分析；③隐含“金标准”的配对设计四格表资料，值得进行统计分析。其次，以第1种情形的“问题与数据”为统计分析的对象，分别采用SAS与R软件进行差异性分析，得出了计算结果，对结果作了解释，并给出了统计和专业结论。 |
| 英文摘要: |
| The purpose of this paper was to introduce the McNemar?s χ2 test and SAS and R software implementation of four-fold table data collected from the matched pairs design. Firstly， it was proposed that there were three situations for the data of four-fold table of the paired design， namely ①the data of paired design four-fold table with the special "gold standard" was worthy of statistical analysis； ②the data of four-fold table of the paired design without the special "gold standard" was not worthy of statistical analysis； ③the data of four-fold table collected from the matched pairs design with implicit "gold standard" was worthy of statistical analysis. Secondly， taking the "problems and data" in the first case as the object of statistical analysis， SAS and R software were used to analyze the differences， the calculation results were given and explained， and the statistical and professional conclusions were also made. |
