Greetings R users,
I have been hoping someone would be familiar with this topic. I understand
fully everything on this list is from the good graces of those who wish to
help. Thanks to those who have helped in multiple circumstances. However,
I wanted to post this question once more. I hope someone will read it and
perhaps have some additional insight into what I may be able to do.
Thank you,
I have been working on running plsda and I would like to have the R2 and Q2
values. I know the function R2 from the 'pls' package will generate
both
R2 and Q2 but they are for each separate class. Is there a way to get the
cumulative R2 and Q2 for the whole model?
R2(pls.new, estimate="all")
Response: B

Again, what I am looking for is a way to get an overall R2 and Q2 values
for the entire model. My thanks to any who can assist me,
Charles
