Spatial dependence: weighting schemes, statistics and models
Description
A collection of functions to create spatial weights matrix
objects from polygon contiguities (including the creation of polygon
lists from imported shapefiles), from point patterns by distance and
tesselations, for summarising these objects, and for permitting their
use in spatial data analysis; a collection of tests for spatial
autocorrelation, including global Moran's I, Geary's C, Hubert/Mantel
general cross product statistic, Empirical Bayes estimates and Assun��o/Reis
Index, Getis/Ord G and multicoloured join count statistics,
local Moran's I and Getis/Ord G, saddlepoint approximations for global
and local Moran's I; and functions for estimating spatial simultaneous
autoregressive (SAR) models.
