Variable-Group Methods for Agglomerative Hierarchical Clustering
Description
A collection of methods for agglomerative hierarchical clustering
strategies on a matrix of distances, implemented using the variable-group
approach introduced in Fernandez and Gomez (2008)
. Descriptive measures to analyze the resulting
hierarchical trees are also provided. In addition to the usual clustering
methods, two parameterized methods are provided to explore an infinite family
of hierarchical clustering strategies. When there are ties in proximity
values, the hierarchical trees obtained are unique and independent of the
order of the elements in the input matrix.
