Introduction,One of the problems which has faced geologists and other scientists in related disciplines for many years is that of defining quantitatively the forms of surfaces and volumes which have been sampled only at discrete points. Many techniques have been devised in attempts to solve this general problem, or to solve restricted subsets of it.

諷刺

Nonparametric Geostatistical Estimation,The reader will probably have seen no necessary connection between the contents of Chapters 2 and 3. Nevertheless, most of the nonparametric principles and methods introduced in Chapter 3 may be used to ease the constraints imposed on geostatistical techniques by assumptions of distribution and spatial homogeneity.

Mining Applications,The majority of estimation problems in mining (and in some other fields) are concerned not with point values but with average values over regions of space (or blocks) of finite size. The value to be estimated is thus the ., over the volume of the block, of the values at all points in the block.

Summary,gularly scattered data, almost all methods in routine use in the mining industry as in other fields are derived from the ideas of standard parametric statistics. The estimators that are used are all related in some way to the arithmetic mean, though the observations are usually weighted to reflect a
