The loadings of a PLS regression are simply the coefficients that are multiplied with the X variables to transform X to the "latent vectors" used in the regression (this is slightly over-simplified). There is no reason why the coefficients of the first component should be larger than the coefficients of other components. (In fact, it is often the case that when one fits too many components (i.e., one starts to model "noise"), the coefficients of the last components get higher and higher.) -- Regards, Bjørn-Helge Mevik ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
