When plotted against each other in a scatterplot, the LDFs form the plane of projection that best illustrates the separation of the groups. See text for details of waveband selection. 3 species of Indo-Pacific corals from the Waikiki Aquarium are also shown in this figure. They are distinguished as coral using the same discriminant functions derived from the Kaneohe Bay data set. Note that the absolute values of the functions and the relative distributions of the groups are different than in Fig.
Numbers indicate distance in meters.
Line transects were two-dimensionally interpolated to produce this map. Brown represents coral, green represents algae, yellow represents sand, and blue represents non-reef area.
