潜在剖面分析和潜在类别分析(Latent Class Analysis, LCA)均属于潜类别模型(Latent Class Model, LCM),即根据个体在观测指标上的反应模式,将其分到不同的类别中。二者的区别在于前者处理连续观测指标,后者处理分类观测指标。 Kunle:Mplus—潜在剖面分析(Latent Profile Analysis, LPA)(合集)149 赞同 · 46 评论文章...
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1-1)。其基本假设是,外显变量各种反应的概率分布可以...

This paper introduces an innovative segmentation methodology for the segment (class) identification model. The method includes a fuzzy segmentation process, which takes into account the varying levels of influence of each attribute on the degree of association with a segment. Five mode choice models ...
潜在类别分析（Latent Class Analysis, LCA）是一种将个体根据分类观测指标的反应特征进行分组的统计方法。这类方法属于潜类别模型（Latent Class Model, LCM），用于识别具有相似模式的群体。要确定分类观测指标，可以是题目得分、维度得分、量表得分等，只要它们是分类变量即可。确定最佳的类别数量，可通过...
Latent Class Models A latent class model (LCM) relates a set of observed discrete multivariate variables to a set of latent variables (latent variables are not directly observed but are rather inferred, mostly through a mathematical model, from other variables that are observed; e.g., quality ...

根据观测指标/外显变量的特征,LCM可以分为潜在类别分析(Latent Class Analysis, LCA)和潜在剖面分析(Latent Profile Analysis, LPA)。 前者处理分类观测指标,后者处理连续观测指标。 潜在剖面分析 简介 潜在剖面分析(Latent Profile Analysis, LPA)可以简单理解为:根据个体对连续观测指标的反应特征,将其划分到不同的类别...
Title:Latent Class Model in STATA 10 Hi, I am analysing a discrete choice data from a choice survey. I am trying to use Latent Class Model to account for heterogeneous preferences. I initially used Nlogit 4 for Latent Class Model (LCM) which was pretty straight forward but it could not ...
