The accident at the Three Mile Island nuclear power plant in 1979 led to an unprecedented set of events with potentially life threatening implications. This paper focusses on the analysis of a longitudinal study of the psychological well-being of the mothers of young children living within 10 miles of the plant. The initial analyses of the data utilize loglinear/logit model techniques from the contingency table literature, and involve the fitting of a sequence of logit models. The inadequancies of these analyses are noted, and a new class of mixture models for logistic response structures is introduced to overcome the noted shortcomings. The paper includes a brief outline of the methodology relevant for the fitting of these models using the method of maximum likelihood, and then the model is applied to the TMI data. The paper concludes with a discussion of some of the substantive implications of the mixture model analysis.
1979年三里岛核电站事故引发了一系列前所未有的事件，这些事件可能危及生命。本文重点分析了一项针对居住在核电站10英里范围内的幼儿母亲心理健康的纵向研究。数据的初步分析使用了列联表文献中的对数线性/对数模型技术，并涉及一系列对数模型的拟合。文中指出了这些分析的不足之处，并引入了一类新的逻辑响应结构混合模型来克服这些缺点。本文简要概述了使用最大似然法拟合这些模型的相关方法，然后将该模型应用于三里岛的数据。本文最后讨论了混合模型分析的一些实质性影响。
