I'm attempting to run a structural equation model that includes an interaction between latent variables. I'm aware that this requires me to use the Integration algorithm; however, something about that algorithm is preventing Mplus from displaying fit indices such as the RMSEA. If the interaction and integration algorithm are removed, the model runs as desired. My code is included below. Do you have any advice on how to fix this problem?
