Top 6 IBM SPSS Amos alternatives

3 Mplus logo

Mplus

Muthén & Muthén

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)

lavaan

Yves Rosseel and contributors

lavaan is an open-source R package for covariance-based structural equation modeling, confirmatory factor analysis, path analysis, and growth modeling. It is aimed...

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
5

OpenMx

OpenMx contributors

OpenMx is an open-source R-based framework for structural equation modeling, matrix algebra, genetic models, and other customizable statistical models. It is intended...

Pros

  • Free and open source, with full access to R programming
  • More customizable for complex and novel model structures than many GUI tools
  • Supports SEM, twin studies, state-space models, and matrix-based estimation

Cons

  • Steeper programming and matrix-algebra learning curve than Mplus
  • Smaller user community and fewer beginner-oriented tutorials than lavaan
  • Less polished for standard point-and-click SEM workflows
6

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
