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 |
