Abstract. Spatial analysis is attracting more attention from Stata users because of the
increasing availability of regional data. In this article, I present an
implementation of hot and cold spot analysis using Stata. I introduce the new
command getisord, which calculates the Getis–Ord (G^*_i(d))
statistic. To implement this command, one only needs the latitude and longitude
of regions as the additional required information. In combination with shape
files, the results obtained from the getisord command can be visually
displayed in Stata. In this article, I also offer an interesting illustration
to explain how the getisord command works.
