调查人员常常希望将大量的人、工作或物体分为数量较少的相互排斥的类别，其中成员具有相似的特征。当以建立互斥簇的分类法的方式完成分组时，其中每个较大单元是下一个从属单元的唯一组合，则簇被称为“分层组”。事实证明，这种分组对于分类目的特别有用。例如，植物和动物可以根据遗传特征进行分层分组；图书馆馆藏按其内容进行分组，以方便信息的存储和检索；出于人事管理的目的，根据特定特征对人员（或工作）进行分组。虽然分组通常会导致一些信息丢失，但它可能会生成新信息并提高考虑大量数据的效率。因此，技术
INVESTIGATORS often desire to group large numbers of persons, jobs, or objects into smaller numbers of mutually exclusive classes in which the members have similar characteristics. When the grouping is done in a manner that establishes a taxonomy of mutually exclusive clusters wherein each larger unit is a unique combination of the next-subordinate units, the clusters are called &dquo;hierarchical groups.&dquo; Such groupings have proved particularly useful for classification purposes. For example, plants and animals may be hierarchically grouped with respect to genetic characteristics; library holdings grouped in terms of their contents to facilitate storage and retrieval of information; persons (or jobs) grouped in terms of specified characteristics for purposes of personnel administration. While grouping ordinarily results in some loss of information, it may generate new information as well as increase the efficiency with which large’ masses of data can be considered. Therefore the tech-
