I found pls.pcr package will give different results if the data are
centered and scaled using scale().
I am not sure about when I should scale my data, and whether the
dependent variable should be scaled. If the dependent variable is
scaled, how I give a prediction to the real data?
I appreciate for any suggestions and comments.
