[Eeglablist] question: determining number of generating sources

[halfordj at musc.edu]

Dear EEGLabList,

In a recently published paper on ICA of clinical EEG (Unsworth 2006 J of Clin
Neurophys; attached to this email), the authors discuss a method for
determining the number of source signals in a blind signal source separation
window by using eigenvalue analysis. Would this be the same as looking at a
plot of the %variances of the ICs produced by an ICA analysis?

Thanks,
Jon
