Dear list, We know that additivity of the variables under study is the basic requirement of any geostatistical study. In practical term, geostatistic works on the variables defined on constant support.
Therefore if our variables (i.e. grade) were derived from the different support (i.e. sample thickness or size), we should use the accumulation (product of thickness or size and the grade) before estimate it. Then the estimated grade is obtained by dividing the estimated accumulation by the estimated thickness or size. May someone has experience regarding the effect of ignoring additivity in any kind of geostatistical estimation compare to the estimation which considering additivity. In other word, how importance of this additivity in geostatistical estimation. Any opinions or references are very welcome. Thank you for attention. Kind regards, --------------- M.
