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