Dear all,
Happy New Year!
Can we regard n=1 in the case of point kriging?
I think there is a trap in the question: How good is estimation using
kriging system that uses a nugget model?
My understanding is that when the spatial autocorrelation of a variable
behaves like a nugget effect, any

SURFER will be giving you the arithmetic mean of the samples which fall

1. How many data points?
2. Do you expect the data to be spatially uncorrelated? (i.e. whatÂ’s
that variable?)
3. If you transform distribution to approximate normal is variogram
still pure nugget?
4. Does regression
