Dear Users, 

 

May I ask if more information is available concerning the ssw command in
spdep? Within the spdep documentation, no references appear, and as such
I'm having trouble understanding exactly what is meant by the term
"dissimilarity" as well as the methods of distance it describes. If
somebody could kindly offer a description of the formula underlying the
sum of dissimilarity I would be sincerely grateful.

 

On a related note, I would like to ask whether spdep can calculate a
local measure of the Sokal statistic (close relative to the Moran's I
and Geary's C). At present, it's not apparent to me whether this
capability exists within the package, and to that end, if any guidance
could be offered towards obtaining either a package or R code that can
calculate the Sokal statistic, it would be much appreciated. 

 

Finally, since this is my first time using this list serve, may I ask
whether a "search" feature for this list serve is available? I would
hate to add already-answered questions to the pile.

 

With sincere thanks in advance for your responses,
