这种情况下,使用潜增长曲线模型拟合我们的数据,或者说在我们的数据中建立潜增长模型将不合适,应该考虑到样本异质性问题,而能解决这一问题的模型之一便是潜类别增长模型(Latent Class Growth Model, LCGM)。 潜类别增长模型可以简单理解为:先将样本分成不同的潜类别组,然后在每个潜类别组中建立潜增长曲线模型去描述...
Fig. 4. Growth Mixture Modeling (GMM). k latent classes are estimated, each having class-specific growth parameters. In GMM, any part of the model can be class-specific (including the means and variances of the latent growth parameters, the indicator variances, etc.). (10)yit=∑k=1Kpkα...
潜类别增长模型（LCGM）旨在解决在一些情况下，群体内个体间存在显著差异，不能满足同质性假设的问题。相比潜增长曲线模型（LGCM），LCGM通过将样本分为不同的潜类别组，并在各组内建立特定的潜增长曲线模型，以此来描述各组内个体特征随时间变化的过程。LCGM实际上是潜在类别模型和潜增长曲线模型的组合...
Income Inequalities in Health: A Latent Class Growth Mixture Model ApproachAndreea MOLDOVAN
A Latent Class Model is a statistical modeling technique that incorporates categorical latent variables, instead of continuous latent variables, to identify distinct subgroups or categories of individuals within a population. This approach is particularly useful in the analysis of longitudinal data and mode...

Latent class growth model (LCGM) Latent class trajectories We performed an unconditional LCGM. Table 4 compares the resulting model fit indices. They were beginning with the most parsimonious one-class model through to the four- class model (Fig. 1), according to BIC, a-BIC, Entropy, ...
在此基础上,学者根据自己的研究兴趣,构建了不同变量的发展轨迹,并进一步思考,是否可以探究不同轨迹之间的相互作用关系,因此提出了平行过程潜在增长曲线模型(parallel-process latent growth curve model, PP-LGCM)。 Vol.2 基本原理PP-LGCM模型图 在潜增长曲线模型的基础上,PP-LGCM的区别在于增加了6条路径线的设置...
