Continuous Time Structural Equation Modelling - Old 'OpenMx'-Based Version R package ctsemOMX version 2.0.1 Original 'ctsem' (continuous time structural equation modelling) functionality, based on the 'OpenMx' software, as described in Driver, Oud, Voelkle (2017) <doi:10.18637/jss.v077.i05>, with updated details in vignette. Combines stochastic differential equations representing latent processes with structural equation measurement models. This package is maintained for consistency with the original 'ctsem' paper, but for the much newer and more capable 'ctsem' package, see <https://cran.r-project.org/package=ctsem>.
