My relatively simple question has to do with modeling the effects of covariates (age, race, gender) on latent variable IVs and DVs.
In the example below where Y is a latent variable, is the effect of age on Y independent of the other covariates included in the model statement? Is this the effect of age, controlling for the rest of the covariates?
Y on age gender race;
Secondarily, if examining a theoretical model within an intervention---do we include treatment arm as a covariate or a grouping variable?
