Liang和Zeger提出了分析重复二元响应的矩量法，普伦蒂斯和Zhao和普伦蒂斯推广了矩量法。在这些估计方程中，提出了重复二元响应之间的相关性模型。我们延长梁和Zeger的方法重复的名义或有序的分类响应之间的相关性模型，特别是，当重复的响应是二进制的，我们的方法减少梁和Zeger的方法。我们的方法用两个数据集来说明。一个数据集包含关节炎自我评估的重复观察结果，这是一个有三个类别的有序变量，是在类风湿性关节炎患者替代治疗的随机比较研究中收集的。第二个数据集是空气污染对健康影响的纵向研究，其中重复有序多项式响应是9岁，10岁，11岁和12岁儿童的喘息状态（无喘息，喘息伴冷，喘息不伴冷）。
Moment methods for analysing repeated binary responses have been proposed by Liang and Zeger, and extended by Prentice and Zhao and Prentice. In these estimating equations, models are proposed for the correlation between the repeated binary responses. We extend Liang and Zeger's method to models for the correlation between repeated nominal or ordinal categorical responses; in particular, when the repeated responses are binary, our methods reduce to Liang and Zeger's method. Our method is illustrated with two datasets. One dataset contains repeated observations of self-assessment of arthritis, an ordered variable with three categories, collected during a randomized comparative study of alternative treatments of patients with rheumatoid arthritis. The second dataset is a longitudinal study of the health effects of air pollution, in which the repeated ordered multinomial response is the wheezing status (no wheeze, wheeze with cold, wheeze apart from cold) of a child at ages 9, 10, 11 and 12 years.
