SPPACK: Stata module for cross-section spatial-autoregressive models

The spmat, spreg and spivreg commands create spatial-weighting matrices, manage spatial-weighting matrices, and estimate the parameters of cross-sectional spatial-autoregressive models with spatial-autoregressive disturbances that may contain additional endogenous covariates. The estimation method is either maximum likelihood or generalized spatial two-stage least squares. The working papers that document these commands are available at http://econweb.umd.edu/~prucha/Papers/WP_spmat_2011.pdf, http://econweb.umd.edu/~prucha/Papers/WP_spreg_2011.pdf, and http://econweb.umd.edu/~prucha/Papers/WP_spivreg_2011.pdf .
