hello, I want to do a test for spatial correlation. I tried it with geary.test() but I don't understand the required input. x= a numeric vector the same length as the neighbours list in listw (my sampled data, I assume) listw= a listw object created for example by nb2listw (well when I check nb2listw() I get to "neighbours - an object of class nb" - but I couldn't figure out, what nb is or how I create such a class
with sp.mantel.mc {spdep} I have the same problem: listw created by nb2listw isn't there a more straight forward method ;-) to check for spatial correlation? like x and y coordinates plus my sampled data? thanks, Martin BTW thanks everybody for their help with my last problem -> [R] regression for several responses - it worked perfectly ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
