2、deling, and analysis of covariance structures 因果模型、潜变量结构方程、协方差结构分析 It is a family of methods for representing, estimating, and testing a theoretical network of (mostly) linear relations between variables 基于理论的变量之间的线性关系 Those variables may be either observable or directly unobservable, and may only be measured imperfectly. 变量可能是可观测的、不可直接观测的、不完美度量的 SEM is a generalization of both regression and factor analysis, and subsumes most linear modeling methods as “special cases.“ SEM是回归和因子分析的集合体,是线性建模方法的特
3、例,Structural Equation Modeling,The main idea behind SEM SEM proceeds by assessing whether a sample covariance or correlation matrix is consistent with a hypothetical matrix implied by the model specified by the user. 样本的协方差或相关系数矩阵 Vs 用户指定模型的假设矩阵 The inputs to SEM are either raw data or sample moments computed from the data, and a model to be evaluated. SEM的输入是原始数据、样本数据、模型 The sample moments will include either variances and covariances or correlations. 样本数据包括方差、协方差、相关系数 The model consists of a n
4、etwork of proposed equations, with some parameters fixed to particular values and others “free to be estimated.”一个特定的方程组、对某些参数进行赋值,6/14/2019,5,Structural Equation Modeling,The main output of SEM Estimates of the designated model parameters参数估计 For the dependent variables, estimates of the proportion of variance explained, often called squared multiple correlations (or SMCs), which are akin to the R2 statistic in regression复相关系数 Overall goodness-of-fit statistics, which assess the overall consist
