Hierarchical structures in the Gross Domestic Product per capita fluctuation in Latin American countries

A description of relations between the yearly fluctuations of the Gross Domestic Product (GDP) per capita of 19 Latin American (LA) countries is presented using either a linear (PCC) or a nonlinear correlation coefficient (NCC). Various time windows have been examined to measure the weights giving rise to links used to built complex networks for which the countries are nodes. The Average Overlap Index (AOI) for LA countries has been calculated for the two correlation coefficients showing that it is rather systematically higher than for the 25 EU countries.
