File Description
grid10x10.dbf: |
Simulated random variables with spatial autocorrelation, base data set, to be joined with grid base map. |
grid100.shp shx dbf: |
Base map with 10 by 10 regular grid, no data. |
grid100s.shp shx dbf: |
Regular 10 by 10 grid with spatially autocorrelated data. |
Type = polygon shape file, unprojected
Observations = 100
Variables = 34
Source
The grid was created in GeoDa. The variables were simulated using R and its spdep package.
Variable |
Description |
PolyID |
Grid cell identifier |
z |
Random variables for standard normal distribution |
zmaxx |
Standard normal variates transformed to follow a spatial moving average with parameter xx (xx is 02, 05, 07, 09 for 0.2, 0.5, 0.7, 0.9) |
ranzmaxx |
Randomly permuted observations matching the variable zmaxx |
zmanxx |
Standard normal variates transformed to follow a spatial moving average with negative parameter xx (same as above) |
ranzmanxx |
Randomly permuted counterpart of zmanxx |
zarxx |
Standard normal variates transformed to follow a spatial autoregressive process with parameter xx (same as above) |
ranzarxx |
Randomly permuted counterpart of zarxx |
zarnxx |
Standard normal variates transformed to follow a spatial autoregressive process with negative parameter xx (same as above) |
ranzarnxx |
Randomly permuted counterpart of zarnxx |
