                     Figures  2(a)  and  2(b)  show  Local  Spatial  Correlation  Scatter  Plot  for
                  colombian cities. This index was calculated using Equation 2 (Zhukiv, 2010) and
                  allows to identify the spatial clusters of territorial entities (municipalities) with
                  high or low values for z − scores.
