Mplus Base Program and Mixture Add-On (32-bit) 7.1

Mplus Base Program and Mixture Add-On (32-bit) by Muthen & Muthen is a statistical software package for latent variable modeling. The Base Program provides a flexible, syntax-driven environment for single-level SEM, CFA/EFA, path analysis, regression with continuous, binary, ordinal, nominal, and count outcomes, mediation and moderation analysis, item response theory models, and latent growth curve modeling. It supports maximum likelihood (including robust variants), weighted least squares (e.g., WLSMV/ULSMV), and Bayesian estimation; handles missing data under MAR; offers fit indices and modification indices; and includes bootstrapping, Monte Carlo simulation, and plotting.

The Mixture Add-On extends the Base Program to finite-mixture modeling, including latent class analysis, latent profile analysis, factor mixture models, and growth mixture models. It provides tools for class enumeration (e.g., information criteria and likelihood-based tests), posterior classification and entropy, and options to relate classes to covariates and distal outcomes.

This 32-bit edition is intended for legacy 32-bit Windows systems and has lower memory limits than the 64-bit edition, which can affect very large models.

Typical users include researchers in psychology, education, public health, and market research who need to model complex relationships and uncover unobserved heterogeneity.

Key features:

• Single-level SEM, CFA/EFA, path analysis, regression, mediation, moderation, and latent growth curves
• Mixture modeling: latent class/profile, factor mixture, and growth mixture
• Supports continuous, binary, ordinal, nominal, count, censored, and zero-inflated outcomes
• Estimators: ML/robust ML, WLSMV/ULSMV, and Bayesian
• Missing data methods, bootstrapping, and Monte Carlo simulation
• Syntax-based input with a Windows GUI; comprehensive output, fit indices, and plots

Mplus Base Program and Mixture Add-On (32-bit) is developed by Muthen & Muthen. The most popular versions of this product among our users are: 5.2, 6.0, 7.0 and 7.1.
