结构方程模型经典资料:Structural Equation Models of Latent Interactions: Evaluation of Alternative Estimation Strategies and Indicator Construction 作者:Herbert W. Marsh;Zhonglin Wen;Kit-Tai Hau 摘要:Interactions between (multiple indicator) latent variables are rarely used because of implementation complexity and competing strategies. Based on 4 simulation studies, the traditional constrained approach performed more poorly than did 3 new approaches—unconstrained, generalized appended product indicator, and quasi-maximum-likelihood (QML). The authors’ new unconstrained approach was easiest to apply. All 4 approaches were relatively unbiased for normally distributed indicators, but the constrained and QML approaches were more biased for nonnormal data; the size and direction of the bias varied with the distribution but not with the sample size. QML had more power, but this advantage was qualified by consistently higher Type I error rates. The authors also compared general strategies for defining product indicators to represent the latent interaction factor. |
