Abstract. We present the spmat command for creating, managing, and storing
spatial-weighting matrices, which are used to model interactions between
spatial or more generally cross-sectional units. spmat can store
spatial-weighting matrices in a general and banded form. We illustrate the use
of the spmat command and discuss some of the underlying issues by using
United States county and postal-code-level data.
