Query: Correlations between the most developed (G7) countries. A moving average
  window size optimisation   Different distance matrices are defined and applied to look for correlations
between the gross domestic product of G7 countries. Results are illustrated
through displays obtained from various graph methods. Significant similarities
between results are obtained. A procedure for choosing the best distance
function is proposed taking into account the size of the window in which
correlation are averaged.
