Simplified parallel coordinate display of all Cnoc Coig data after partial grand tour. This is particularly clear in the .25-.355 axis. Simplified scatterplot matrix of all Cnoc Coig data after partial grand tour. The coloring is as in Figure 14. A density plot of the circled scatterplot is shown in the upper right.
Bright colors represent many points and dark colors only a few points.
Due to overplotting it appears that the same points have been selected more than once. In reality, a visible point sometimes represents a larger number of samples and it is already highlighted if just one of these samples is selected. We apply the classification rule of training data to the entire data set of 226 samples. Those points are classified by using the classification rule based on the training data for variable .355 - .50mm. Final classification tree for separating all 226 sand samples by site.
