omega vs. alpha explanation
.../RGM_results/psych:omega.graph/omega.graph_002_big.png>,
and
alpha uses average inter-item correlations.
1. What I don't understand is, in what condition, omega reliability
coefficient would be higher than alpha coefficient, and vice versa?
2. Can I assume if the correlations between the subfactors and the
variables are higher, the omega coefficient would also be higher (as shown
in the omega graph<http://rgm2.lab.nig.ac.jp/RGM_results/psych:omega.graph/omega.graph_002_big.png>
)?
Any advice is appreciated!
Thanks.
