Help: PLSR
...total
variance in X).
Because the trainSet has been scaled before training, I think Xtotvar
should be equal to 14, but unexpectedly Xtotvar = 16562, and the
values of Xvar are also very big and sum of Xvar = 16562. Why does
this type of result occur? for the reason of kernel algorithm?

test for equality of two data sets with multidimensional variables
...ely. Which R functions could do
this kind of test? I just find some functions could do for one
dimension, but no for multidimension. Some one suggests bartlett.test,
but it seems just works for one dimension. Do you know which ones
could do that, or I have to do R programming by myself?

plot.lda(drug.lda,
