⚠️There's a newer version (1.1.1) of this package.Take me there.

MplusAutomation (version 0.6-2)

Automating Mplus Model Estimation and Interpretation

Description

The MplusAutomation package leverages the flexibility of the R language to automate latent variable model estimation and interpretation using Mplus, a powerful latent variable modeling program developed by Muthen and Muthen (www.statmodel.com). Specifically, MplusAutomation provides routines for creating related groups of models, running batches of models, and extracting and tabulating model parameters and fit statistics.
