Hi Mplus veterans!

I tried to fit a two-level item bifactor random item response model. The below are protocol scripts I wrote for the model. I will greatly appreciate if you can provide some feedback on my scripts.

Thank you!

Usevariables are y1-y6;
CATEGORICAL ARE y1-y6;
CLUSTER IS cluster;

PROCESS = 2;
ESTIMATOR = bayes;
MODEL: %within%
