analysis is the clustering, or grouping, of large data sets (e.g
chemical and/or pharmacological data sets) on the basis of similarity
criteria for appropriately scaled variables that represent the data of
interest. Similarity criteria (distance based, associative, correlative,
probabilistic) among the several clusters facilitate the recognition of
patterns and reveal otherwise hidden structures.
