This may be a simple question.
I am doing a path analysis and have a categorical indicator variable with 4 levels. From what I have read on here, it looks like I need to create three dummy codes 0/1, just like in regression. Then what? Do I create an ON statement with all dummy codes - i.e., y1 ON dummy1 dummy2 dummy3? How do I interpret the output for these codes?
Your sample size may be too small especially if the items have floor or ceiling effects. You do not want empty cells in the bivariate frequency tables for pairs of items. You might check out these bivariate frequency tables as a first step.

Thank you. The items are categorized into clusters according to theory. So I did polychoric correlation for one of the clusters using SAS. And I get pretty good correlations (above .53). Not sure if it is equvalent to checking the bivariate frequency tables. So if I want to use a CCFA on this cluster only. Do you think it will work using Mplus?
