Canonical correlation analysis is, like co-inertia analysis, a symetric method.
I.e., both tables play the same role : there is not a set of dependent variables
and a set of explanatory/independent ones.

No. PLS2 is mostly usefull when you have many independent variables. You
cannot use Cancor in this case.
