Dear Dr. Muthen, I am running a single group CFA with categorical observed indicators. My ultimate goal is to do a multiple group comparison. But first, I am trying to fit my model for each group. To do so, in mplus I just wrote Y ON X1-X5 and ran the model for each group seperately. The results produced factor loadings, thresholds, factor variance, and residual variance. My questions : 1- Do I need to constrain my thresholds in a single group CFA? 2- I did not get scale factors in my single group CFA. Do I need to specify scale factros and/or maybe constrain them? 3- In the output, I also did not see the factor mean. Shoud I specify it in my model? In general, could you please let me know what should I specify in my model for a single group CFA with categorical outcomes?
