who can tell me the reason why it is different on calculating Moran's I using ARCGIS, Geoda and R?
...t the different result of Moran's between ARCGIS and Geoda, R, why?
ARCGIS:spatial statistics tools:spatial autocorrelation(Moran's I)=0.0343
GeoDa:Moran's I=0.1539
R:Moran I statistic =0.153905049
The key arguments in R that i use:
ccc<-read.gwt2nb("ccc.GWT",region.id=ID)
ccc2<-nb2listw(ccc, glist=NULL, style="W", zero.policy=TRUE)
moran.test(LIVES,ccc2,alternative="two.sided")
what is the problem? I'm very confused by it?
Thanks very very much!
