Structural equation modeling software tools | Mathematical modeling data analysis
In general, Structural Equation Modeling (SEM) is defined as "a class of methodologies that seeks to represent hypotheses about the means, variances and covariances of observed data in terms of a smaller number of structural parameters defiend by a hypothesized underlying model".
Provides functions to conducting univariate and multivariate meta-analysis using a Structural Equation Modelling (SEM) approach. metaSEM is an R package that implements a two-stage structural equation modeling (TSSEM) approach to conducting fixed- and random-effects meta-analytic structural equation modeling (MASEM) on correlation/covariance matrices. Many of the techniques available in this SEM package can be easily extended to meta-analysis.
Enables structural equation modeling (SEM) with continuous data. lavaan is an R package providing a collection of tools that can be used to explore, estimate, and understand a wide family of latent variable models, including factor analysis, structural equation, longitudinal, multilevel, latent class, item response, and missing data models. The software can serve for estimating multiple multivariate statistical models, such as path analysis, confirmatory factor analysis, structural equation modeling and growth curve models.
Assists in structural equation modelling (SEM) employing OpenMx. umx supports rapid development, modification, and comparison of models, as well as both graphical and tabular reporting. It gathers functions for path-based SEM and matrix-based multi-group twin modelling. This tool can be useful to learning and undertaking behavior genetics. It can serve to utilize the power of structural modeling in a work.
