Finding Groups in Data: An Introduction to Cluster Analysis Leonard Kaufman, Peter J. Rousseeuw
Publisher: Wiley-Interscience

Hierarchical cluster analysis allows visualization of high dimensional data and enables pattern recognition and identification of physiologic patient states. 5 Wage bargaining coordination and government involvement. Rousseeuw, Finding Groups in Data: An Introduction to Cluster Analysis, John Wiley & Sons, Hoboken, NJ, USA, 2005. 5.1 Direct government involvement in wage setting. 4 Centralisation of wage bargaining. The basic idea of TDA is to describe the “shape of the data” by finding clusters, holes, tunnels, etc. 18 Our data provide information from 1995 and 2006 for 23 European countries, plus the US and Japan. The information obtained from the organizational survey enabled us to characterize PHC organizations. Cluster analysis is special case of TDA. In addition to the edges of the graph, we will . Because the clustering method failed to separate the patient data into groups by obvious traditional physiological definitions these results confirm our hypothesis that clustering would find meaningful patterns of data that were otherwise impossible to physiologically discern or classify using traditional clinical definitions. Our goal was to establish an organizational classification which would group PHC organizations based on their common characteristics. The organizational data were analyzed .. To extract more topological information— in particular, to get the homology groups— we need to do some more work. I think Ron Atkin introduced this stuff in the early 1970′s with his q-analysis (see http://en.wikipedia.org/wiki/Q-analysis).
