local_moran: Calculate the Local Moran's I Statistic

In sfdep: Spatial Dependence for Simple Features

Calculate the Local Moran's I Statistic

Description

Moran's I is calculated for each polygon based on the neighbor and weight lists.

Usage

local_moran(x, nb, wt, alternative = "two.sided", nsim = 499, ...)

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().
alternative	default "two.sided". Should be one of "greater", "less", or "two.sided" to specify the alternative hypothesis.
nsim	The number of simulations to run.
...	See ?spdep::localmoran_perm() for more options.

Details

local_moran() calls spdep::localmoran_perm() and calculates the Moran I for each polygon. As well as provide simulated p-values.

Value

a data.frame containing the columns ii, eii, var_ii, z_ii, p_ii, p_ii_sim, and p_folded_sim. For more details please see spdep::localmoran_perm().
