Constructor Details

Dendrogram

public Dendrogram(int[][] merge,
 double[] height)

Constructor.

Parameters:

merge - an n-1 by 2 matrix of which row i describes the merging of clusters at step i of the clustering. If an element j in the row is less than n, then observation j was merged at this stage. If j >= n then the merge was with the cluster formed at the (earlier) stage j-n of the algorithm.

height - a set of n-1 non-decreasing real values, which are the clustering height, i.e., the value of the criterion associated with the clustering method for the particular agglomeration.
