Though usually, in taxonomy, clusters are nothing more than the result of an algorithm, graph theory makes it possible to define clusters properly in mathematical terms. One convenient definition — as shown in Subsections 3.1.2 and 3.2.

Thus, cluster analysis is raised from a tool of exploratory statistics to a helpful method of inference statistics.
