print.listw

The function prints summary measures for links in a neighbours list. If a
matrix of coordinates is given as well, summary descriptive measures for
the link lengths are also printed. Print and summary functions are also available for <code>"listw"</code> weights list objects, also reporting constants (S0, S1, S2) used in inference for global spatial autocorrelation statistics such as Moran's I, Geary's C, join-count tests and Getis-Ord G.

spatial

A collection of functions to create spatial weights matrix
objects from polygon 'contiguities', from point patterns by distance and
tessellations, for summarizing these objects, and for permitting their
use in spatial data analysis, including regional aggregation by minimum
spanning tree; a collection of tests for spatial 'autocorrelation',
including global 'Morans I' and 'Gearys C' proposed by 'Cliff' and 'Ord'
(1973, ISBN: 0850860369) and (1981, ISBN: 0850860814), 'Hubert/Mantel'
general cross product statistic, Empirical Bayes estimates and

these measures is described in 'Bivand' and 'Wong' (2018)

spatial 'Durbin' models based on linear models ('Koley' and 'Bera' 2023)
<doi:10.1080/17421772.2023.2256810>.
From 'spdep' and 'spatialreg' versions >= 1.2-1, the model fitting functions
previously present in this package are defunct in 'spdep' and may be found
in 'spatialreg'.
