The article by Jeremy Miles provides a comprehensive review of four widely used Structural Equation Modelling (SEM) software packages: LISREL 8.20, EQS 5.6, AMOS 3.6, and SEPath. The review focuses on their suitability for teaching environments rather than technical capabilities. Each software is evaluated based on its user interface, input methods, output features, and specific functionalities. - **LISREL 8.20**: Known for its extensive documentation and powerful matrix manipulation, LISREL has introduced new input methods like path diagrams and projects, making it more user-friendly. It supports various fit indices and can handle ordinal data. - **EQS 5.6**: Similar to LISREL in terms of input methods, EQS is user-friendly and can perform additional analyses like t-tests and ANOVA. It offers robust procedures for handling ordinal and skewed data. - **AMOS 3.6**: A newcomers to SEM, AMOS is designed for teaching and ease of use. It features bootstrapping and Full Information Maximum Likelihood (FIML) estimation for missing data, making it robust for various analyses. - **SEPath**: Part of the Statistica package, SEPath is highly intuitive and user-friendly. It excels in handling standard errors for correlation matrices and provides detailed and organized output. The article concludes that while each software has its strengths, LISREL is the most popular, EQS is powerful for non-normal data, AMOS is ideal for missing data and bootstrapping, and SEPath is excellent for standard errors. All four programs are suitable for both teaching and research, but LISREL is the most widely used in theoretical articles.The article by Jeremy Miles provides a comprehensive review of four widely used Structural Equation Modelling (SEM) software packages: LISREL 8.20, EQS 5.6, AMOS 3.6, and SEPath.
