Columbus OH spatial analysis data set - old numbering

Description

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).

Usage

data(oldcol)

Format

This data frame contains the following columns:

AREA_PL: computed by ArcView (agrees with areas of polygons in the “columbus” data set
PERIMETER: computed by ArcView
COLUMBUS.: internal polygon ID (ignore)
COLUMBUS.I: another internal polygon ID (ignore)
POLYID: yet another polygon ID
NEIG: neighborhood id value (1-49); conforms to id value used in Spatial Econometrics book.
HOVAL: housing value (in $1,000)
INC: household income (in $1,000)
CRIME: residential burglaries and vehicle thefts per thousand households in the neighborhood
OPEN: open space in neighborhood
PLUMB: percentage housing units without plumbin
DISCBD: distance to CBD
X: x coordinate (in arbitrary digitizing units, not polygon coordinates)
Y: y coordinate (in arbitrary digitizing units, not polygon coordinates)
AREA_SS: neighborhood area (computed by SpaceStat)
NSA: north-south dummy (North=1)
NSB: north-south dummy (North=1)
EW: east-west dummy (East=1)
CP: core-periphery dummy (Core=1)
THOUS: constant=1,000
NEIGNO: NEIG+1,000, alternative neighborhood id value
PERIM: polygon perimeter (computed by SpaceStat)

Details

The row names of COL.OLD and the region.id attribute of COL.nb are set to columbus$NEIGNO.
