Hi Mach -
Jan Merks isn't the only one who has questioned the fundamentals of
geostatistics. You might also like to look at the work of Robert F. Shurtz.
Perhaps the most interesting is a slim volume published by the Mining &
Metallurgical Society of America, "A Geostatistical Monograph" (in 1997, I
believe, though the book isn't dated). This is in the form of a debate
between Robert Shurtz (criticising geostats) and Harry Parker (defending
geostats).
If you want alternatives to geostats, there are plenty on offer. Problem is,
of course, that after thirty-something years geostatistics has become the
'accepted wisdom' in the mining community, and you have an uphill struggle
to justify using any other method. Unfortunately, also, any geostatistical
practitioner who uses a fancy new nonlinear kriging method has much less of
a struggle even if that new method is little better than alchemy. Linear
kriging does actually have some nice mathematical properties if its
assumptions are satisfied and when used properly ('best linear unbiased
estimator' and all that) but what many users seem to forget is that, as soon
as they tweak the method, they lose some or all of these properties. In my
opinion many of the more exotic variants of kriging are worse than using
non-geostatistical methods because they encourage - wrongly - a belief that
they are in some ways superior simply because they are known as "xxxxx
kriging".

Subject: [ai-geostats] Geostats Scam?
Hi,
This guy (Jan W Merks) seems to devote his life trying
to prove that Geostatistics is a scam... If it's true
I'm gonna start looking for alternatives.

Anyone has a point of vue on this?
