Hi,
I am using a 'listw' object (see package spdep) to store weights to
compute differentbstatistics, and I wonder whether it is possible to
define weights as, say, the inverse of the distance (or any other
function based on the centroids, for example).
Futhermore, is it efficient to use one of these objects when
all the areas are linked one another? Is it better to use a square nxn
matrix in this case?
Thank you for your help.
