Weather and climate vary from place to place, soil varies at every scale at which it is examined, and even man-made attributes - such as the distribution of pollution - vary. The techniques used in geostatistics are ideally suited to the needs of environmental scientists, who use them to make the best of sparse data for prediction, and top plan future surveys when resources are limited. Geostatistical technology has advanced much in the last few years and many of these developments are being incorporated into the practitioner's reperto 410 0$aStatistics in practice. 606 $aGeology$xStatistical methods 606 $aEnvironmental sciences$xStatistical methods 608 $aElectronic books. 615 0$aGeology$xStatistical methods. 615 0$aEnvironmental sciences$xStatistical methods. 676 $a550.72 676 $a550/.7/2 700 $aWebster$b R$0862800 701 $aOliver$b M.
