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, including regional aggregation by minimum spanning tree; a
collection of tests for spatial autocorrelation, including global Moran's
I, APLE, Geary's C, Hubert/Mantel general cross product statistic,
Empirical Bayes estimates and Assuncao/Reis Index, Getis/Ord G and
multicoloured join count statistics, local Moran's I and Getis/Ord G,
saddlepoint approximations and exact tests for global and local Moran's
I; and functions for estimating spatial simultaneous autoregressive (SAR)
lag and error models, impact measures for lag models, weighted and
unweighted SAR and CAR spatial regression models, semi-parametric and
Moran eigenvector spatial filtering, GM SAR error models, and generalized
spatial two stage least squares models.
