Uses x,y coordinates to produce distance-based spatial weight matrices useful for spatial econometric regressions. The user is asked to input x and y coordinates, as well as a lower and upper bound threshold for the neighborhood.
The code is adapted from a previous version by Shawn Bucholtz of the USDA. A correction is made to set the (i,i) th elements (the diagonals) equal to zero.
Unlike other similar programs, this one can be used on very large datasets.
