However, to perform SEM effectively, you need a reliable and user-friendly software package that can handle different types of data, models, and methods. One of the most popular and widely used software packages for SEM is Lisrel.
What is Lisrel 9.1 and why do you need it?
Lisrel is a software program that was developed by Professor Karl Jöreskog in 1970 as a general method for estimating linear structural equation systems. Since then, Lisrel has evolved into a comprehensive software package that can perform various types of SEM, such as confirmatory factor analysis, path analysis, latent variable modeling, multilevel modeling, generalized linear modeling, and more.
Lisrel 9.1 is the latest version of Lisrel that was released in 2012 by Scientific Software International, Inc. (SSI). It includes several new features and improvements that make it more efficient, flexible, and user-friendly than previous versions.
Some of the advantages of using Lisrel 9.1 are:
It can handle both continuous and categorical variables, as well as complete and incomplete data from simple random or complex survey designs.
It can estimate models using different methods, such as maximum likelihood, weighted least squares, generalized least squares, diagonally weighted least squares, unweighted least squares, or partial least squares.
It can provide robust estimates of standard errors and chi-square tests under non-normality or non-independence of observations.
It can perform multiple imputation or full information maximum likelihood to deal with missing data.
It can test various types of hypotheses, such as model fit, parameter significance, indirect effects, moderation effects, mediation effects, invariance tests, etc.
It can generate various types of output, such as path diagrams, tables, graphs, matrices, residuals, modification indices, etc.
It has a graphical user interface (GUI) that allows users to specify models using drag-and-drop or point-and-click operations.
It has a syntax editor that allows users to write commands using Simplis or Lisrel syntax.
It has a help system that provides detailed explanations of concepts, commands, options, examples, references, etc.
If you are interested in learning more about SEM and applying it to your research or practice, you should definitely consider using Lisrel 9.1 as your software tool.
