LISREL 8.3

LISREL is a statistical software package developed by Karl Jöreskog and Dag Sörbom. It is used for the estimation of LInear Structural RELationships and for many other types of multivariate analysis, such as factor analysis, multiple regression, path analysis, analysis of mean structure and multisample analysis.

The LISREL model in its most general form consists of two parts: the measurement model and the structural equation model.
The measurement model specifies how latent variables or hypothetical constructs depend upon or are indicated by the observed variables. It describes the measurement properties (reliabilities and validities) of the observed variables.
The structural equation model specifies the casual relationships among the latent variables, describes causal effects, and assigns the explained and unexplained variance.

LISREL 8.3 contains the command language SIMPLIS, which uses plain English input commands. The LISREL package also includes PRELIS 2, a program for multivariate data screening and data summarization, which can be used as a preprocessor for LISREL.

IMPORTANT POINTS TO REMEMBER:

To Start LISREL
Click on the LISREL 8.3 icon in the Applications folder.

Building a LISREL Project Interactively
The LISREL for Windows program allows the user to build a LISREL project interactively by making use of a set of menus. The project is stored as LISREL system data (*.lpj), which may later be loaded and modified.  A project is also associated with its own set of syntax (*.ls8), output (*.out), path diagram (*.pth) and matrix files.

 

Modifying a LISREL Project
Project specifications may be modified through the appropriate submenus.  Click on Next to advance to the next menu, if necessary, or click on OK to exit the menus.  The modifications should be applied and displayed in the current project window.

Using the Path Diagram
If the program is successfully executed, the Path Diagram window is invoked (assuming this option was checked in the Selections window).  One may modify the path diagram by deleting, fixing or adding paths.

Building a LISREL Project Using an External Syntax File
Users can also utilize an external LISREL syntax file to build a LISREL project.
