I am fairly new to SEM in general, and I've been trying to figure out the best approach to modeling interaction effects between latent variables in OpenMx.
Umbach et al (2017) [5] and Cortina et al (2021) [6] both provide an overview of the existing methods for identifying latent interactions.
At least product indicator approaches, such as the constrained approach described by Kenny & Judd (1984) [7] and the unconstrained approach by Marsh et al. (2004) [8] should be possible to model in OpenMx. Can for example the indicator products be computed as mxAlgebra
objects? What about distribution analytic approaches such as LMS (Klein and Moosbrugger, 2000 [9])?
Any example scripts or tutorials would be appreciated.
