Hi everyone,
I am interested in running a confirmatory factor analysis (CFA) to SEM model with five variables. The model includes two latent variables measured by multiple-item scales and three observed variables measured by only one single-item scale (separately).
How can I run CFA in STATA to this model?
Do I need to fix loadings and error variance to the single-item variables before running the CFA?
Are there any other special treatments to be done in this case?

Thank you in advance
Netty
