circular

nrow

ncol

The function generates k-ahead and k-behind weighting matrices as in Kelejian and Prucha (1999)

spatial

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.
