Dear Bjørn-Helge,
Sorry, I wrote the wrong number of observation. It should be 1184.
I saw on the book that variance is defined by sd^2. If variation is a
different concept from variance and defined by sd^2*(n-1) ? Since I
formerly took variance and variation as the same.
Thank you,
Shengzhe

Hello,
I have a data set with 15 variables (first one is the response) and
1200 observations. Now I use pls package to do the plsr as below.
trainSet = as.data.frame(scale(trainSet, center = T, scale = T))
trainSet.plsr = mvr(formula, ncomp = 14, data = trainSet, method = "kernelpls",
Hello,
I have a data set with 15 variables (first one is the response) and
1200 observations. Now I use pls package to do the plsr with cross
validation as below.
trainSet = as.data.frame(scale(trainSet, center = T, scale = T))
trainSet.plsr = mvr(formula, ncomp = 14, data = trainSet, method = "k
