Spatial dependence: weighting schemes, statistics and models
Description
A collection of functions to create spatial weights matrix
objects from polygon contiguities, 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, and Getis/Ord G, 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. Was formerly the three packages: spweights, sptests, and spsarlm.
