Cluster dendrogram of the 14 selected variables from the Selwood dataset using repeated K -fold cross-validation. Three distinct clusters can be noted (shown in red, green, and yellow rectangles). One sub-cluster can be seen within the red cluster (shown in a blue rectangle). The red and green numbers are p-values of a given cluster; they indicate how well the cluster is supported by data (see [31] for details). ⁺Additional variables selected by repeated K-fold cross-validation compared to the C¹C².
