Extended Agglomerative Hierarchical Clustering
Description
A comprehensive collection of linkage methods for agglomerative
hierarchical clustering on a matrix of proximity data (distances or
similarities), returning a multifurcated dendrogram or multidendrogram.
Multidendrograms can group more than two clusters when ties in proximity data
occur, and therefore they do not depend on the order of the input data.
Descriptive measures to analyze the resulting dendrogram are additionally
provided.
