Two forms 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 standard edge or vertex), which express the neighbour structure between the grids. The difference between two spatial weight matrices is whether or not the in-situ relation (i.e. the diagonal of the load matrix) is considered.

And leaving is just not an possibility.
