NAVAL-SEM is an award-winning, free and open-source offline Structural Equation Modeling (SEM) platform supporting PLS-SEM and CB-SEM workflows. Designed for researchers, PhD scholars, professors, and analysts, it provides visual model building, measurement assessment, structural model analysis, and reproducible research workflows without subscriptions or cloud dependency.
Features include:
• PLS-SEM & CB-SEM
• Bootstrapping, mediation, moderation & conditional process analysis
• HTMT, AVE, Composite Reliability, Cronbach's Alpha, Fornell-Larcker
• VIF, f² effect size, indirect effects, Q² blindfolding, PLSpredict, CVPAT
• Multi-Group Analysis (MGA), HOC, MICOM
• IPMA, NCA, nonlinear effects, FIMIX-PLS, PLS-POS, endogeneity checks
• EFA, CVI, measurement validation, fsQCA
• APA report generation and R/Python/Lavaan export
Fully offline and available for Windows, macOS, and Linux. Recognized with the SourceForge Rising Star Award.
