Plots from the PLS model

A plot of the score vectors against each other, e.g. against tj, shows the positions of the projected object points in the plane spanned by the PLS vectors in ths X space, and a plot of U2 against Uj shows the same for the Y space. These plots are therefore similar to the score plots from principal components analysis. 

A plot of Uj aginst tj shows the linear relation between the PLS components. The slope is the coefficient of the inner relation.
