OpenMx is free, full-featured, open source, structural equation modeling (SEM) software. OpenMx runs within the R statistical programming environment on Windows, Mac OS-X, and Linux computers. The rationale for developing OpenMx is discussed along with the philosophy behind the user interface. The OpenMx data structures are introduced - these novel structures define the user interface framework and provide new opportunities for model specification. Two short example scripts for the specification and fitting of a confirmatory factor model are next presented. We end with an abbreviated list of modeling applications available in OpenMx 1.0 and a discussion of directions for future development.
OpenMx是一款免费、功能齐全的开源结构方程建模（SEM）软件。OpenMx可在Windows、Mac OS-X和Linux计算机上的R统计编程环境中运行。文中讨论了开发OpenMx的基本原理以及用户界面背后的理念。介绍了OpenMx的数据结构——这些新颖的结构定义了用户界面框架，并为模型规范提供了新的机会。接下来展示了两个用于验证性因子模型规范和拟合的简短示例脚本。最后，我们列出了OpenMx 1.0中可用的建模应用程序的简略清单，并讨论了未来的发展方向。
