(Linear Structural Relations) is a statistical software package developed by Scientific Software International (SSI). Since its debut in the 1970s, it has become the foundational tool for Structural Equation Modeling. While newer, more user-friendly programs exist today, LISREL remains synonymous with SEM in academic literature; if you are studying psychology, education, sociology, or business, you will likely encounter citations of studies built on LISREL.

The software generates a comprehensive list of fit statistics, including Chi-Square, RMSEA, CFI, and GFI, which are essential for validating research models. Limitations to Consider
Learning LISREL syntax (SIMPLIS) teaches you the underlying logic of SEM better than "point-and-click" tools. Path Diagrams: Limitations of the Student Version
is a free, open‑source R package for latent variable analysis. It can estimate path analysis, confirmatory factor analysis, structural equation modelling, and growth curve models. The results from lavaan are "very close, if not identical, to those reported by current commercial SEM programs, like MPLUS, AMOS, EQS or Lisrel". lavaan is actively developed and aims to implement all the state‑of‑the‑art capabilities available in commercial packages.
This is particularly useful because:
Provides comprehensive fit indices (RMSEA, CFI, TLI, Chi-Square), parameter estimates, and modification indices. Limitations of the Student Version
