Put the Q2 for PLS-DA and sPLS-DA

[Kim-Anh Le Cao]

See email below attached. We do have some concerns about the Q2 for a multiple regression case. But for a simple regression (with PLS-DA) it is less of an issue.

Priority major? for me? It's gonna take time since I'm on V6 at the moment

[Kim-Anh Le Cao]

I am happy to put it minor + I just had to put something :) But I don’t think it would take too much time as it is a generalisation of the Q2 but for PLS-DA only – anyway we can talk about it, not stress.

The status of the Q2 is "OK"?

[Kim-Anh Le Cao]

The status is 'OK' for a simple regression (i.e. Y = 1 variable) which is the case of PLS-DA. To be discussed with Benoit but I think it is ok. The issue is more when we are performing a multiple regression (e.g. PLS) where everything seems to break loose.
