The present paper discusses two rather different types of partitioning techniques that still have the same property of monotone invariance. (Author)

Paper is an attempt to extend the hierarchical partitioning algorithms and to emphasize a general connection between these clustering procedures and the mathematical theory of lattices. (Author)

The role of the coauthor relationship in the structure of informal communications networks within disciplines is explored, and the validity of coauthor graphs used to map these relationships is tested for both small and large databases. (CLB)

The purpose of this paper is to suggest a technique of cluster analysis which is similar in aim to the Interactive Intercolumnar Correlation Analysis (IICA), though different in detail. Two methods are proposed for extracting a single bipolar factor (a "contrast compenent") directly from the initial similarities matrix. The advantages of this…

Addressed to institutional researchers, this report from California's Chabot College presents information on National Center for Education Statistics (NCES) data sets. Included is a discussion on how these data sets can be used to create peer groups of U.S. colleges, and to produce statistics on major student variables for each of these groups.…

This monograph attempts to describe the rural population as reported in the 1960 Census of Population and to evaluate the residence categories used. The hypothesis that the proximity to large metropolitan centers plays a crucial role in determining the characteristics of rural areas is applied. Substantive and analytical portions of the monograph…
