SPATDWM: Stata modules for US State and County spatial distance matrices


  • Yihua Calvin Yu

    () (Oklahoma State University)


Following Scott Merryman (2005), this package contains two Stata data files that are spatial distance matrices for 48 U.S. contiguous states and 3109 U.S. counties, respectively. The third file includes a description of the two distance formula. These two Stata files can be used with Maurizio Pisati's STB-60 sg162 "Tools for spatial data analysis." The sample dataset and do-file used in Scott Merryman can be borrowed to demonstrate their usage. Due to their size, these files are in a zip file.
