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...
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...

If the discrete-valued variable is observed, then eqn [18] reduces to a linear regression model with both main effects and time-interaction effects as yielded by the levels of that variable. Therefore, the defining feature of the latent growth model in eqn [18] is that the class to which...

The present work is an introduction to Latent Class Growth Modelling (LCGM). LCGM is a semi-parametric statistical technique used to analyze longitudinal data. It is used when the data follows a pattern of change in which both the strength and the direction of the relationship between the ind...
