Global C Permutation Test

Global C Permutation Test

Usage

global_c_perm(
  x,
  nb,
  wt,
  nsim = 499,
  alternative = "greater",
  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().

nsim

number of simulations to run.

alternative

default "two.sided". Should be one of "greater", "less", or "two.sided" to specify the alternative hypothesis.

allow_zero

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

...

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

Value

an object of classes htest and mc.sim
