Object  →  DendrogramNode

Use the DendrogramNode class to access the results of a HierarchicalClusterAnalysis in a dendrogram representation. A dendrogram is a tree-like structure that shows the complete history of how the analysis was performed.

The IsLeaf property indicates whether the cluster is a leaf node (an observation from the original data set), or a merged cluster. The ObservationIndex returns the index of this observation. The LeftChild and RightChild properties specify the two clusters that were merged, while DistanceMeasure returns the distance between the two merged clusters. Level returns the number of nodes between the current node and the root node. The root node is at level 0.

A dendrogram is also useful to give a graphical representation of the results. The Position property gives the horizontal position of the node. The leaf nodes (observations) have integer positions that correspond to their dendrogram order and can be used as one coordinate. It is centered over the two clusters that were merged. The DistanceMeasure or Level properties can be used as the other coordinate.
