Hi,
I would like to know what is the difference between FAMD and PCA+quali.sup? As I see the manual [1], it says that FAMD is between PCA and MCA which deals with both qualitative and quantitative variables. On the other hand, with PCA() it is also possible to pass quali.sup to the function. I use that with one qualitative variable column and it puts the categories as the center of mass for the individuals.

So, I would like to know what problem can FAMD solve that PCA+quali.sup isn't capable of?


Regards,
Mahmood
