Inverse relationship between interpolation and prediction. (Top) Interpo-
lation axes in biplot plane. Interpolation is finding for the red sample point in the full
space its representation at the tip of the arrow in the biplot space. (Bottom) The axes
shown are the original axes passing through the biplot plane. Prediction is inferring the
values of the original variables for a point in the biplot space.
