Partial Least Squares Biplot
Adds a Biplot to a Partial Lest Squares (plsr) object.
Biplot.PLSR(plsr)
plsr |
A plsr object from the PLSR function |
Adds a Biplot to a Partial Lest Squares (plsr) object. The biplot is constructed with the matrix of predictors, the dependent variable is projected onto the biplot as a continuous supplementary variable.
An object of class ContinuousBiplot with the dependent variables as supplemntary.
