Does anyone know if you can run invariance testing if you only have access to summary data.
I have one data-set with full item level information and can only access summary data on another data-set (correlation matrix, maybe means and standard deviations too).
I'm hoping to try to conduct invariance testing for a latent variable across both of these datasets.
I can't find any specific information on the limitations of summary data in mplus. I'd appreciate it if anyone could answer the specific question above or point me in the right direction to understand the limitations around summary data.
Thanks in advance.
