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

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 |
