Figure 20. 1-dimensional sliced inverse regression plot showing classification of dogs
into groups based on lipoprotein profile analysis after the diet change. The vertical line
represents the line that separates the 2 groups based on their lipoprotein profile analysis.
The LDA value provides a ranking value for each dog. The dogs represented by the dots
that are at the bottom of the graph are the dogs of the control group. Their lipoprotein
profiles plot them all to the right of the vertical line. The dogs represented by the dots at
the top of the graph are the dogs of Group 1 (with hypertriglyceridemia) after the diet
change. Nine of the 16 dogs are now classified to the right of the vertical line together
with the control dogs, suggesting that they are considered normal based on their
lipoprotein profile analysis. The remaining 7 dogs are classified separately from the
control dogs even after the diet change. Note that there is a clear separation between
dogs of Group 1 that responded to the diet change and those that did not.
