We construct a binary contiguity weighting matrix (mathbf{W}) in which the (i,j) elements (corresponding to the relative position of region (i) with respect to region (j)) take value 1, (bar{w}_{ij}=1), if the involved regions share their borders, at least partially; and take value 0, (bar{w} _{ij}=0), otherwise.
