This text provides an introduction to 
clustering methods, including both hierarchical and non-hierarchical methods. It shows how clustering can be used to interpret large quantities of analytical data and it discusses the relation of clustering to other pattern recognition technologies.  A two-level approach is used to provide both a qualitative understanding of the philosophy, advantages and disadvantages of clustering, and a quantitative understanding for readers who want a strong mathematical background. A worked 
example  and a list of computer packages are included.  |
