The application is illustrated using data with a known common factor structure. The results demonstrate the capabilities of the program for conducting specification searches in SEM. The programming codes are provided as open-source R functions.
结构方程模型(Structural Equation Modeling,SEM)是一种能基于变量之间的协方差矩阵分析多变量之间结构关系的多元统计分析方法,也被称为协方差结构模型。该方法是因子分析和多元回归分析的结合,可用于分析被测变量与潜在变量之间的结构关系,替代多重回归、通径分析、因子分析、协方差分析等分析方法。结构方程模型能在一次分...

This can be done by comparing the fit of a (nested) model with constraints to the fit of the more general model using a chi-square difference test (Δχ2) 这儿给大家介绍两种常见的可以在随机截距交叉滞后模型中加的限制条件: 一个是交叉滞后系数的时间不变性,就是我们可以将所有的滞后系数固定为一...

The very crux of GEE is instead of attempting to model the within-subject covariance structure, to treat it as a nuisance and simply model the mean response.方差函数与均值函数 假设我们有独立响应变量 与自变量矩阵，且与 有如下关系：其中被称作均值函数，你把这个μ(⋅)想办法移到等号左边它就成了...

As discussed above, one of the limitations in model testing in SEM is that the proposed model may not be exactly correct. Using Digman’s (1997) higher-order factor structure as an example, the proposed model hypothesizes no double loading on the items and that the measurement errors are un...
