Two varieties of spatial weight matrices aiding additional evaluation are given within the repository. We calculate the spatial weights based mostly on the Queen contiguity (sharing a common edge or vertex), which express the neighbour construction between the grids. The difference between two spatial weight matrices is whether the in-situ relation (i.e. the diagonal of the burden matrix) is taken into account.

And leaving just isn’t an possibility.
