when using saving FScores from a growth mixture model, among other information two sets of individual latent growth paramteres are saved. The second set uses the prefix c_. What is the difference between the two? Thanks.
If I measure the same factor over time (with identical indicators), and want to introduce the change in this factor over time to predict the outcome of interest at each time, how do I do this? Is it possible to subrtact the factor scores between times for each individual when specifying the model?
