The SSN package provides tools to fit generalized linear models with spatial
autocorrelation using normal likelihood methods (including REML) and quasi-likelihood
for Poisson and Binomial families. The spatial formulation is described in Ver Hoef
and Peterson (2010) and Peterson and Ver Hoef (2010). The spatial data must be formatted
in a geographic information system (GIS) prior to importing it into R. Two custom
ArcGIS toolboxes (v 9.3.1) have been provided to format the data: the Functional Linkage
of Water Basins and Streams(FLoWS; Theobald et al. 2006) and the Spatial Tools for
the Analysis of River Systems (STARS) tooset (Peterson 2011).References
