目的:探讨广义估计方程在CT显示方法研究中的应用。方法:采用SAS软件的GENMOD过程,应用广义估计方程方法分析CT显示方法研究实例。结果:给出了广义估计方程SAS程序,并对参数估计和两两比较结果进行解释。结论:广义估计方程能有效的分析CT显示方法研究中反应变量为两分类或多分类的非独立数据。
Objective: To discuss the application of generalized estimation equation in the study of CT display method. Methods: The SAS software GENMOD process, the application of generalized estimation equation method analysis of CT display examples. Results: The generalized estimation equation SAS program is given, and the parameter estimation and pairwise comparison results are explained. CONCLUSION: The generalized estimation equation can effectively analyze the non-independent data in which the response variables are two-category or multi-category in the study of CT display method.
