PackageDescription | GNU R spatial dependence: weighting schemes, statistics and models
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
Moran's I, APLE, Geary's C, Hubert/Mantel general cross product
statistic, Empirical Bayes estimates and Assunção/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. |
