I am working on my dissertation and facing a great obstacle. I want to perform a moderated mediation and it doesn't work. I have tried all the instructions posted on lavaan forums in order to create an r synthax...I have even tried mplus...but with no results.
The actual struggle is that my predictor variable is a latent one estimated by two manifest variables. The model includes a moderator, a mediator and a dependent variable ( all manifest variables).
Have a nice day!
