SpatialStats : A TIBCO Spotfire S+ Package for Analysis of Spatial Data

SpatialStats is an object-oriented toolkit for analysis of spatial data.
SpatialStats offers a wide collection of tools, including:

 * Variogram and correlogram calculation
 * Fitting of theoretical variogram models 
 * Graphical exploration for geometric anisotropy
 * Variogram clouds with intercative point identification
 * Side by side boxplots of a variogram cloud
 * Ordinary and Universal Kriging with prediction errors
 * Point and block kriging predictions
 * Finding of nearest neighbors of a point using a quad-tree
 * Measures of Spatial Correlation such as Moran, Geary, as well as Monte
   Carlo estimates of their permutation distribution 
 * Determination of spatial neighbors of several orders and computation of
   corresponding spatial weight matrix
 * Fitting of spatial linear (Generalized Least Squares) regression models
   for covariance families including: Conditional Spatial Autoregression 
   (CAR), Simultaneous Spatial Autoregression (SAR), and Moving Averages (MA) 
 * Likelihood ratio test estimation for spatial linear models
 * Sparse Matrix operations, including determinants
 * Hexagonal binning for large 2-dimensional data
 * Rayplots with confidence arcs
 * Generation and analysis of spatial point pattern objects
 * Empirical distribution functions of origin-to-point and point-to-point
   nearest neighbor distances
 * Ripley's K-Function for spatial point patterns
 * Kernel estimation of intensity for spatial point patterns
 * Simulation of a spatial point process for distributions including:
   Poisson (homogeneous and non-homogeneous), Matern's Cluster, Strauss,
   and Strauss Sequential Inhibition
 * Functions to compute Polygonal areas and membership
 * Delaunay's Triangulations
