摘　　要：为了减少对安全生产领域重复测量数据的统计分析过程产生的偏差,将广义估计方程(GEE)引入统计分析过程计分析.通过对GEE方法的理论与适用性的分析,探讨使用GEE解决在安全生产重复测量调查研究中数据的组内相关性问题.研究表明:GEE能够克服针对同一研究对象多次研究过程中难以避免的同一对象之间的相关性问题,利用了重复测量数据中的测量结果,充分利用了有效数据,减少了损失,对安全生产领域重复测量数据的研究结果的评价更为准确.In order to reduce the deviation caused by the statistical analysis process of repeated measurement data in the field of safety production,the generalized estimation equation(GEE) is introduced into the statistical analysis process.Based on the analysis of the theory and applicability of GEE,this paper discusses how to use GEE to solve the problem of intra group correlation of data in repeated measurement in safety area.It shows that GEE overcome the problem of correlation between the same object in the process of multiple studies on the same on the same research object,make use of the results of each measurement in the repeated measurement data,make full use of the effective data,the loss,and evaluate the research results of the repeated measurement data in the field of safety production more accurately.
