Global C Test

Global C Test

Usage

global_c_test(x, nb, wt, randomization = TRUE, allow_zero = NULL, ...)

Arguments

x

A numeric vector.

nb

a neighbor list object for example as created by st_contiguity().

wt

a weights list as created by st_weights().

randomization

default TRUE. Calculate variance based on randomization. If FALSE, under the assumption of normality.

allow_zero

If TRUE, assigns zero as lagged value to zone without neighbors.

...

additional arguments passed to spdep::moran.mc()

Value

an htest object
