Clustering History Report

The Clustering History table contains the clustering history.

Lists the numbers of clusters that result after the joining indicated by the Leader and Joiner is performed. The number of clusters begins with the first join, when there are n - 1 clusters, where n is the number of objects. The report lists the number of clusters in decreasing order until all objects are contained in one cluster. In this way, the Clustering History follows the order of the dendrogram from left to right.

Distance

The distance between clusters, calculated according to the distance method that you select on the launch window. See Method for Distance Calculation.

Leader

A representative of the first cluster in the dendrogram being joined. The cluster order and the representative shown in the Leader column is a consequence of how the data are sorted and has no intrinsic meaning.

Joiner

A representative of the second cluster in the dendrogram being joined. The cluster order and the representative shown in the Joiner column is a consequence of how the data are sorted and has no intrinsic meaning.
