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, 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 Assun��o/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.
