Graphing Nonlinear Relations Among Latent Variables from Structural Equation Mixture Models

Contains a graphical user interface to generate the diagnostic plots proposed by Bauer (2005; ), Pek & Chalmers (2015; ), and Pek, Chalmers, R. Kok, & Losardo (2015; ) to investigate nonlinear bivariate relationships in latent regression models using structural equation mixture models (SEMMs).

Graphing nonlinear latent variable interactions in SEMM.


Contains functions plotSEMM_setup, plotSEMM_contour, and plotSEMM_probability, which generate the diagnostic plots proposed by Bauer (2005) to investigate nonlinear latent variable interactions in SEMM using LISREL output.
