Structural Equation Modelling (SEM) is a statistical technique based on factor analysis and multiple regression. This article reviews four commonly used SEM packages: LISREL 8.20, EQS 5.6, AMOS 3.6, and SEPath. The review focuses on their suitability for teaching rather than technical details. All programs were tested on Windows 95, a 166 MHz Pentium, with 32 MB RAM. LISREL, developed by Joreskog and Sorbom, has been around longer than most SEM programs. It has extensive documentation and a new version with a user-friendly interface. LISREL 8.20 includes a path diagram input and project input, making it easier for beginners. It also supports ordinal data and provides various fit indices. EQS, developed by Peter Bentler, is user-friendly and supports a range of analyses beyond SEM, including t-tests and ANOVA. It has a similar interface to LISREL and supports path diagrams and syntax. EQS has improved stability and is suitable for beginners. AMOS, developed by Jim Arbuckle, is a newer program with a user-friendly interface and intuitive features. It supports bootstrapping and missing data analysis. AMOS is designed for teaching and is easy to use, though it lacks some features like those in LISREL and EQS. SEPath, developed by James Steiger, is part of the Statistica package. It has a smooth interface and provides accurate standard errors. It lacks some features like modification indices but is user-friendly and suitable for beginners. All four programs are suitable for teaching and research. They can import various file types and are relatively simple to use, though SEM has a steep learning curve. LISREL is commonly used in published research, while EQS is catching up. The review highlights the strengths and weaknesses of each program, emphasizing their suitability for different user needs.Structural Equation Modelling (SEM) is a statistical technique based on factor analysis and multiple regression.
