Another distinction often made in the literature of numerical taxonomy is that between divisive and agglomerative approaches . 在文獻的版值分類方法中,還存在另一個區別,即劃分法和聚合法。
The rapid development of numerical taxonomy over the past fifteen years has contributed to the development of parallel methods in plant ecology . 數值分類學的迅速發展,雖是近十五年的事,但它對植物生態學中相應方法的發展作出了貢獻。

Numerical taxonomy is a classification system in biological systematics which deals with the grouping by numerical methods of taxonomic units based on their character states. It aims to create a taxonomy using numeric algorithms like cluster analysis rather than using subjective evaluation of their properties.
