Nijgh-Wolters-Noordhoff Universitaire, 1973. — 122 p.This book contains a survey of a number of techniques of clustering analysis. The merits and demerits of the procedures described are also discussed so that the research worker can make an informed choice between them.
These techniques have been published in a very great number of journals which are not all easily accessible to the sociologist. This difficulty is compounded because developments in the different disciplines have occurred almost entirely independently from each other; reference is made only sporadically in a piece of literature to the literature of other disciplines. This is one of the reasons why the survey contained in this book cannot be complete. In addition to this the techniques described have been selected according to their relevance to sociological (and psychological) research.
As far as classification of the techniques is concerned, a classification following the field of application of the methods has been opted for (for other classification criteria see, for example, Williams and Dale, 1965 and Lance and Williams, 1967a). After the general introduction, chapter one goes on to discuss a number of coefficients which indicate relative similarity between objects since most clustering techniques take their point of departure from a matrix of similarity coefficients. In the second chapter attention is paid to a number of methods which can be used for clustering variables as well as objects, and the third chapter treats methods for clustering just objects. A special chapter has been devoted to the methods of McQuitty because of their systematic development and very characteristic point of departure. Finally, the fifth chapter demonstrates via an illustrative example the application of some methods.Coefficients for Defining the Degree of Similarity Between Objects
Methods Developed for Forming Clusters of Variables or Objects
Methods of Forming Clusters for Objects
Methods for the Construction of Types Following McQuitty
Some Applications
