本文讨论了纵向研究中可能出现的分类变量重复观测的统计分析方法。描述了两种一般类型的模型：边际模型，表示在每个场合的边际分布的响应，和transitionalmodels，表示在连续场合的结果状态之间的转移概率。概念和技术的差异进行了讨论，并审查了最近的工作推进这两种方法。这两种方法说明通过分析反复观察的间隔历史的呼吸道症状“持续喘息”在青春期前的儿童。
This paper discusses statistical methods for the analysis of repeated observations of categorical variables as they might arise in longitudinal studies. Two general types of models are described:marginalmodels that give representations for the marginal distribution of response at each occasion, andtransitionalmodels that give representations for the transition probabilities between outcome states at successive occasions. The conceptual and technical differences are discussed and recent work advancing both approaches is reviewed. The two approaches are illustrated through analysis of repeated observations on interval history of the respiratory symptom ‘persistent wheeze’ in preadolescent children.
