Before I Kriged with a pure nugget variogram I would ask:
1. How many data points? 2. Do you expect the data to be spatially uncorrelated? (i.e. whats that variable?) 3. If you transform distribution to approximate normal is variogram still pure nugget? 4. Does regression of variable (both raw and approximately normal) on x + y + (z?) show a correlation? 5. If you group the data into 3 to 10 geographic areas does ANOVA say mean is the same (both raw and approximately normal) Robert (Bob) L.
