Help with PLSR with jack knife
...he plsr using the commands:
BHPLS1 <- plsr(GroupingList ~ PCIList, ncomp = 10, data = PLSdata, validation =
"LOO")
and
BHPLS1 <- plsr(GroupingList ~ PCIList, ncomp = 10, data = PLSdata, validation =
"CV")
I have also used the following command to obtain the loadings
BHPLS1_Loadings <- loadings(BHPLS1)
Now I am unsure of how to utilise these to identify the significant variables.
Do I need to use any loops?
str(BHPLS1_Loadings)
