1. Chip ID is the identification number of simulated chip.
2. MEAN is the average of intensity measurements of gene expression for each chip.
3. SD is the standard deviation of intensity measurement of gene expression for each chip.
4. CV is the coefficient of variation of intensity measurements of gene expression for each chip.
5. GEODEX^[1] is a geography index calculated by model (1).
6. GEODEX^[2] is a geography index calculated by model (2) (N_B = 36).
