Mplus is statistical software for structural equation modeling, latent variable analysis, multilevel modeling, mixture modeling, and longitudinal data analysis. It is used...
Pros
- Handles SEM, growth models, mixture models, multilevel models, and complex survey designs in one application
- Stronger support for categorical and non-normal outcomes than many GUI-focused SEM tools
- Includes robust missing-data, Bayesian, and Monte Carlo simulation capabilities
Cons
- Paid licensing is more expensive than R-based alternatives such as lavaan and OpenMx
- Input syntax has a steeper learning curve than AMOS or SmartPLS
- Limited data management and general-purpose statistical features compared with Stata
From $195 (student license)

Pros
- Free and open source, unlike Mplus
- Excellent syntax for CFA, path analysis, mediation, and latent growth models
- Integrates directly with R data handling, visualization, and reporting tools
Cons
- Less comprehensive than Mplus for mixture, complex survey, and specialized categorical models
- Requires R programming rather than offering a standalone graphical interface
- Bayesian modeling is less integrated than in Mplus
Free, open source

IBM SPSS Amos
IBM
IBM SPSS Amos is graphical software for structural equation modeling, confirmatory factor analysis, path analysis, and latent variable models. It is designed...
Pros
- Visual path-diagram interface is more approachable than Mplus syntax for beginners
- Integrates with SPSS datasets and common SPSS workflows
- Good coverage of conventional CFA, path analysis, and mediation models
Cons
- Less capable than Mplus for mixture, complex survey, and advanced categorical models
- Windows-focused availability limits platform flexibility
- Less suitable for highly automated or text-based reproducible workflows
Paid; quote-based

SmartPLS
SmartPLS GmbH
SmartPLS is software for partial least squares structural equation modeling, confirmatory composite analysis, and related multivariate methods. It is aimed at applied...
Pros
- More accessible graphical workflow than Mplus for PLS path models
- Strong support for prediction-oriented PLS-SEM and composite constructs
- Includes bootstrapping, mediation, moderation, and importance-performance analysis
Cons
- PLS-SEM is methodologically different from Mplus's covariance-based SEM
- Less suitable for latent growth, mixture, multilevel, and complex survey models
- Advanced features require a paid plan
Freemium, paid plans available
