Convergence and cluster structures in EU area according to fluctuations in macroeconomic indices
Mircea Gligor, Marcel Ausloos
The cluster analysis methods are used in order to perform a comparative study of 15 EU countries in relation with the fluctuations of some basic macroeconomic indicators. The stati…
Cluster Expansion Method for Evolving Weighted Networks Having Vector-like Nodes
Marcel Ausloos, Mircea Gligor
The Cluster Variation Method known in statistical mechanics and condensed matter is revived for weighted bipartite networks. The decomposition of a Hamiltonian through a finite num…
Clusters in weighted macroeconomic networks : the EU case. Introducing the overlapping index of GDP/capita fluctuation correlations
Mircea Gligor, Marcel Ausloos
GDP/capita correlations are investigated in various time windows (TW), for the time interval 1990-2005. The target group of countries is the set of 25 EU members, 15 till 2004 plus…
Cluster structure of EU-15 countries derived from the correlation matrix analysis of macroeconomic index fluctuations
M. Gligor, M. Ausloos
The statistical distances between countries, calculated for various moving average time windows, are mapped into the ultrametric subdominant space as in classical Minimal Spanning…
Statistical distances between countries and cluster structures in EU area according to macroeconomic indices fluctuations
Mircea Gligor, Marcel Ausloos
The paper applies some recent developments of network analysis in order to perform a comparative study of EU countries in relation with the fluctuations of some macroeconomic indic…
