boston {spdep} | R Documentation |
The boston.c
data frame has 506 rows and 20 columns. It contains
the Harrison and Rubinfeld (1978) data corrected for a few minor errors
and augmented with the latitude and longitude of the observations. Gilley
and Pace also point out that MEDV is censored, in that median values
at or over USD 50,000 are set to USD 50,000. The original data set
without the corrections is also included in package mlbench
as
BostonHousing
. In addition, a matrix of tract point coordinates
projected to UTM zone 19 is included as boston.utm
, and a sphere
of influence neighbours list as boston.soi
.
