Usage

kfolds2Chisqind(pls_kfolds)

Arguments

pls_kfolds

a k-fold cross validated partial least squares regression glm model

Value

list

Individual PChisq vs number of components for the first group partition

list()

...

list

Individual PChisq vs number of components for the last group partition

Note

Use cv.plsRglm to create k-fold cross validated partial least squares regression glm models.
