Model 1 can be described graphically in terms of a path diagram (or a graphical model) in which manifest variables are not connected to each other directly, but indirectly through the common source X. The latent variable is assumed to explain all of the ...
Model selectionSummary. In many areas of medical research, such as psychiatry and gerontology, latent class variables are used to classify individuals into disease categories, often with the intention of hierarchical modeling. Problems arise when it is not clear how many disease classes are ...
高于阈值的分类的比例:这里 90.18%(分别为 61.29%)的第 1 类(分别为 2)的后验概率大于 70%。 本文摘选《R语言潜类别混合效应模型(Latent Class Mixed Model ,LCMM)分析老年痴呆年龄数据》
Latent Class Model
潜在类别模型(Latent Class Model, LCM; Lazarsfeld & Henry, 1968)或潜在类别分析(Latent Class Analysis, LCA)是通过间断的潜变量即潜 在类别(Class)变量来解释外显指标间的关联,使外显指标间的关联通过潜在类别变量来估计,进而维持其局部独立性的统计方法(见图11)。其基本假设是,外显变量各种反应的概率分布可以...
With a latent-class model, each individual belongs to a single latent class, which determines the person's set of response probabilities for the observed, or manifest, variables. A more general model, proposed herein, adds a single parameter and involves drawing, separately and independently for ...

As an example, we used the LC cluster model to develop a segmentation of current bank customers based upon the types of accounts they have. Separate models were developed specifying different numbers of clusters and the model selected was the one that had the lowest BIC statistic. This criteria...
