The COL.OLD data frame has 49 rows and 22 columns. The observations are
ordered and numbered as in the original analyses of the data set in the
SpaceStat documentation and in Anselin, L. 1988 Spatial econometrics: methods and models, Dordrecht: Kluwer.
Unit of analysis: 49 neighbourhoods in Columbus, OH, 1980 data.
In addition the data set includes COL.nb, the neighbours list
as used in Anselin (1988).
