Periods described by 12 attributes are the subject of discrimination. Such an approach opens new possibilities in time series analyses. Several taxonomie algorithms were used, along with two completely new numerical methods. Using these methods, the authors mark out substantially different phases in the development of demographic processes in GDR.polinfo:eu-repo/semantics/openAccessArtykuł
