Not sure where to post this, so I just started a new thread (sorry).

I was wondering what is the conceptual difference between a simple multiple (logistic) regression, and a regression where my predictors are loaded on latent factors. Does the latter make sense?

Y on X1-X10; !Y is binary
F1-F3 by X1-X10(*1);
Y on X1-X10;

The output estimates were different (Y on X1-X10), but their signs and significance are similar (some became smaller, some became bigger with F1-F3).

What is the effect of loading X1-X10 to F1-F3 in X's prediction of Y?
Can I say that X1-X10's prediction of Y is influenced by F1-F3?

Any input would be appreciated. Thanks!

In the model using BY you are imposing a model, that is, putting a restriction on the correlations of the marginal distribution of the 10 x's while the other model allows them to be freely correlated.

The model with BY is a bit strange because you don't relate the f1-f3 factors to other variables such as Y.
