摘要为了分析一组m个二分项目的反应模式的“可扩展性”,我们引入了一个模型,在该模型中,群体中的给定个体是“内在可扩展的”或“内在不可扩展的”(相对于m个项目),并且有d种不同类型的“内在可扩展的”个体。有了这个模型,使用方法已经开发的准独立的列联表中的研究,我们展示了如何(a)测试模型是否适合观察到的数据,(B)估计的比例,本质上可扩展的(和不可扩展的)个人,和(c)估计的分布之间的d个不同的规模类型的本质上可扩展的个人。
Abstract To analyze the “scalability” of the observed response patterns for a set of m dichotomous items, we introduce a model in which a given individual in the population is either “intrinsically scalable” or “intrinsically unscalable” (with respect to the m items), and there are d different types of “intrinsically scalable” individuals. With this model, using methods already developed for the study of quasi-independence in contingency tables, we show how to (a) test whether the model fits the observed data, (b) estimate the proportion of intrinsically scalable (and unscalable) individuals, and (c) estimate the distribution of the intrinsically scalable individuals among the d different scale types.
