I will suggest Jan to read some basic geostatistics theory, and more particularly on stationary random functions. But, Jan, you are all right, geostatistics is a particular case of mathematical statistics. Please, find the Matheron thesis and read it.....

> All I really want to know is what happened to the variance of a single distance-weighted average when the latter metamorphosed into an honorific kriged estimate and the kriging variance of a SET of kriged estimates became a cornerstone of geostatistics. Readers should try to figure out what would happen to geostatistics if each and every kriged estimate does indeed have its own variance? I submit that geostatistics would simply mutate into mathematical statistics! Could a first generation geostatistician please explain why the variance of a single distance-weighted average-cum-kriged estimate was dismissed, ignored or otherwise lost?
