double_center_distance_matrix {spatialRF} | R Documentation |
Generates a double-centered matrix (row and column means are zero) from the weights of a distance matrix (see weights_from_distance_matrix()
) and a distance threshold. This is a required step before the computation of Moran's Eigenvector Maps.
