gwr.morantest {spgwr} | R Documentation |
The function returns Leung et al. (2000) three moment approximation for Moran's I, for a gwr object calculated with argument hatmatrix=TRUE. This implementation should not be regarded as authoritative, as it involves assumptions about implied methods and about estimated degrees of freedom.
gwr.morantest(x, lw, zero.policy = FALSE)
x |
a gwr object returned by gwr() with argument hatmatrix=TRUE |
lw |
a listw object created for example by nb2listw in the spdep package |
zero.policy |
if TRUE assign zero to the lagged value of zones without neighbours, if FALSE (default) assign NA |
a “htest” object with the results of testing the GWR residuals
