We have four time-points, and at each time-point there are two indicators. Is it possible to use the two manifest indicators per time-point to create one latent variable per time-point, and run a growth mixture model on those four latent variables?
If that is possible, suppose that we are actually missing one manifest indicator at one time-point. Is it possible to create a latent variable in place of that manifest indicator? A drawing of our model, as well as our attempted script, is attached. We are getting the following error:
Error: The job for model 'Growth Mixture Model' exited abnormally with the error message: Objective function returned an infinite value at iteration 0.1.
