Hi Lise,
If you run a stochastic simulation with a kriging algorithm you can reproduce the experimental variogram. But if you run a kriging estimation procedure, you won the bet :) Meanwhile I'm sure you'll get more and better replies.
Greettings, Manuel
PS: sorry Lise for replying twice.
Hi Lise
If you did a Gaussian simulation - you should be able to reproduce the variogram (at least when it is done without conditioning data - the data mess it up to some extent).
But kriging produces a smooth function and, if you calculate a variogram of the krigedmap, will always have quadratic behavior at the origin...irrespective of the original variogram
So you win...Cheers! (or Slainte as we say if my part of the world)

Subject: [ai-geostats] variograms of interpolated data
Hello,
Could someone please settle a beer-bet with a
classmate. He says that I should be able to reproduce
the variogram model used for kriging a dataset by
running a variogram analysis on the interpolated data.
I say he's all wet. Who wins the beer? Thanks and I'm
sorry I can't award the judges a free one (especially
if you find in my favor!). Merci!
Lise
