I didn’t realize that was in there. I’m guessing Ben added it at some point.

# Help with factor analysis (latent variable model)

Just of curiosity, why (in the context of your data) do you compute the above?

Thanks

Hi!

This operation aims just to create a covariance matrix with estimated correlations between factors but diagonal fixed to one. This the Φ of classical factor analysis formulation. But I just realized that using direcly a constrained correlation matrix should work, without an unnecessary operation!
