Hi Lise,
The best way to sort this out is to try it :-)
However, the nugget effect will certainly disappear from a variogram
constructed on krigged data (simulated data are supposed to keep it
though). Sill, range and anisotropy should remain, as well as, I think,
the general shape of the variogram model (i.e. spherical, exponential,
etc.).
As a conclusion, you can't retrieve the _exact_ variogram model only by
doing variography on krigged data, but you can retrieve something very
very close.
IMHO, you should give it a try and share the beer ;-)
Cheers
Nicolas

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
