Although there exists a value at location x that could be measured, geostatistics considers this value as random since it was not measured, or has not been measured yet.
Ačkoliv na souřadnicích x existuje hodnota, kterou by bylo možné měřit, tak geostatistika tuto hodnotu považuje za čistě náhodnou, jelikož nebyla naměřena (nebo zatím nebyla naměřena).
