Hi, I'm examining longitudinal meausrement invariance, and need to calculate chi-sq diff testing. I'm using an MLR estimator with Mplus V.3.0. I'm confused by the steps on your website for chi-sq diff testing using SB chi. I'm stuck at step 1!:Estimate the nested and comparison models using both ML and MLM or MLR. How do I get both the ML and MLR chi-sq? On my output I only get one chi-sq value and the scale-correction factor?
