Parameters for geostatistical analysis of log-transformed qPCR data of FeOB and MOB taxa and percentage of moisture content.
| Parameter | Nugget | Sill | Spatial dependence | p-Range (m) p < 0.05 |
|---|---|---|---|---|
| Moisture | 1.856 | 6.514 | 0.71 | 5.38 |
| FeOB | None | 0.922 | 1.00 | 12.57 |
| Type Ia | 0.261 | 0.396 | 0.34 | 6.34 |
| Type Ib | 0.047 | 0.179 | 0.74 | 14.78 |
| Type II | 0.148 | 0.218 | 0.32 | 2.07 |
The nugget quantifies the amount of variability at distance of zero, the sill is the value where the variogram levels off, the spatial dependence indicates the proportion of variability of the data that was modeled, the practical range (p-range) equal to the distance at which 95% of the sill has been reached.
