W artykule podjęto próbę wykorzystania metod taksonomicznych do klasyfikacji krajów Unii Europejskiej. Do podziału państw europejskich na klasy o podobnym rozwoju gospodarczym wykorzystano klasyczne metody taksonomiczne: metody hierarchiczne, takie jak metoda najbliższego sąsiedztwa oraz metoda Warda, metody optymalizacyjne: metoda k-średnich oraz k-medoidów. (fragment tekstu)

We consider the problem of determining the structure of clustered data, without prior knowledge of the number of clusters or any other information about their composition. Most clustering done in practice is based largely on heuristic and intuitive procedures. One of the widely used class of methods involves hierarchical agglomerative clustering (single-link, Ward method) and relocation methods (k-means). We review a general methodology for model-based clustering that provides a principal statistical approach to these issues. The article presents application of all these methods in the economic analysis- clustering of the EU countries, which is comparatively rare. (original abstract)
