Diana, Yes, you may have to roll up your sleeves for this one, as I don't think it is automated in Stata, or any other program: Jensen, A. R., & Weng, L. (1994). What is a good g? Intelligence, 18, 231-258. Nelson, J.M., Canivez, G.L., Lindstrom, W., & Hatt, C.V. (2007).

If you mean higher order factor analysis, i.e., imposing a factor structure on the factor covariance matrix, I suspect the answer is not at the present time. You could always extract the factor correlation matrix from an oblique rotation and work with the Schmid-Leiman transformations yourself. > > However, for a confirmatory model I suspect you could set this up in -gllamm- but I'd sure want to test it carefully on examples that I was certain about. I believe there are some examples of this in the PROC CALIS documentation in SAS/Stat, for instance.... Just checked. It's a replicated example of some data from Thurstone from R. P.
