Continuous Time SEM - 'OpenMx' Based Functions
Description
Original 'ctsem' (continuous time structural equation modelling)
functionality, based on the 'OpenMx' software, as described in
Driver, Oud, Voelkle (2017) , with updated details in vignette.
Combines stochastic differential equations representing latent processes with
structural equation measurement models. These functions were split off from
the main package of 'ctsem', as the main package uses the 'rstan' package as a backend now --
offering estimation options from max likelihood to Bayesian.
There are nevertheless use cases for the wide format SEM style approach as offered here,
particularly when there are no individual differences in observation timing and the
number of individuals is large. For the main 'ctsem' package, see .
