How many components to choose - group PCA?
Does anyone have a paper they could point me to for a method to
figure out how many components to choose when doing PCA? I see the
default in CONN is set to 20, with a dimensionality reduction of
64. I have only 30 subjects in my resting state study, and I am
wondering how to choose the number of components for a small group
like this.
Thank you!
