Hi, I have been asked to look through some analysis for a collegue. One of the models I have been given uses an observed variable (obs10) as a dependent variable. The model specification is shown below.
latent1 BY obs1 obs2 obs3; latent2 BY obs4 obs5 obs6 obs7; latent3 BY obs8 obs9; obs10 ON latent1 latent2 latent3;
I have heard that it is ok to use observed variables in this way, but am struggling to see how obs10 plays a different role in the model to that of an indicator variable that loads on all three latent variables. Is there a statistical difference in the ON command as opposed to the BY command? Are you able to recommend any papers/resources that give information about using measured variables as dependent variables in this way?
