I need to do EFA (evolving factor analysis) to seperate spectrum
having several sub factors. What kind of m-file and toolbox should I
use for?


One of previous student said that he used "evolvfa" m-file, but he
couldn't remember the name of toolbolx. I guess that maybe
"statistics toolbox", but I am not sure.


If any of you can give me a help, I really be appreciated.
