FindClusters and the distance and dissimilarity functions have been added to the built-in Mathematica kernel.
SupDistance is replaced by ChessboardDistance.
CorrelationDissimilarity is replaced by CorrelationDistance.
CosineAngleDissimilarity is replaced by CosineDistance.
RussleRaoDissimilarity is replaced by RussellRaoDissimilarity.
A new Hierarchical Clustering Package has been created.
Syntax for FindClusters is the same as in Statistics`ClusterAnalysis` in Version 5.2:
Many functions from Statistics`ClusterAnalysis` are now found in the Hierarchical Clustering Package:
