I have a SEM with a dichotomous DV, 3 latent IVs and several covariates. I am using WLSMV. I wanted to see probability curves. I have run plot 2. Then I viewed the graph and chose: 1) item characteristic curves 2) for a single item 3) chose my DV 4) for all categories 5) choose the IV of interest Since the plot holds all of the other variables at their means, I would anticipate that I could run this separately for each of my 3 latent IVs and at "0" the probability should be the samesince all variables are at their means. However, I see slight differences at "0." Why is this? Thanks, Tammy 


This may have to do with the covariates. Please send the inputs, data, outputs, and your license number to support@statmodel.com.
