Estimating latent variable interactions and quadratics: The state of this art
综述了检测潜变量交互与二次效应的技术，重点介绍了非线性结构方程分析的最新进展，并为实证研究者提供了实用建议。
Because there is little guidance for substantive researchers, the paper reviews the techniques for detecting latent variable interactions and quadratics. After examining plausible research situations where including these nonlinear variables might be appropriate, the paper describes the available detection techniques. Recent advances in nonlinear structural equation analysis are given particular attention, and suggestions for substantive researchers are made.
