One approach: do a lit search using Monte Carlo and Factor Analysis on Psych Lit. That should come up with many citation that will give the details. The general approach is to write a computer program that generates random data with the specified intercorrelation matrices. It's standard practice to vary parameters such as sample size, number of variables, underlying populations and so forth. You run some large number of reps, say 10,000 and get averages, variances, etc.

(btw, I used to do Monte Carlo simulations if you're interested in a consultant)
