abstract: Functions for fitting Cliff-Ord-type spatial autoregressive models with
  and without heteroskedastic innovations using Generalized Method of Moments estimation
  are provided. Some support is available for fitting spatial HAC models, and for
  fitting with non-spatial endogeneous variables using instrumental variables.
