Hi all,
I have been trying to figure out exactly how the empty EV option works. I ran two analyses, one where the empty EV option was used and the other, where the empty EV option was not. That is to say, one analysis modeled the evs A, B, C, and D(empty) while the other modeled A, B, and C only. Subtracting both the cope and varcope images between the two analyses produced no differences, so it seems as though running the analysis with the empty ev option checked estimates the model as though there were not an ev there at all. My only question is that the degrees of freedom appear to be different between the two analyses. I am correct in assuming that this doesn't have any consequences for the results?
Thanks!
