Multilevel CFA? PreviousNext

I am interested in running a multilevel CFA, but not very familiar with Mplus but HLM.

I have a two level dataset where peer raters (level 1 variables) are nested within target students (level 2). The datasets are two separate datasets that contain the target student ID as the matching variable. Can you please let me know whether I need to transform these two datasets to run a multilevel CFA in Mplus?

Many thanks and happy holidays,

All data must be in one data set. Cluster level variables take on the same value for all cluster members. See Example 9.7 in he user's guide and the data for that example.

Ok, thanks. I am still not clear what to do if I want to have cluster level continuous variables (student level self-reports)as part of the CFA with level 1 variables (peer ratings of students on cooperation).

If you have a cluster level continuous variable, each member of the cluster will get the same value for that variable, so if it is y, the data will be:

cluster y
