It is also worthwhile to look at a log-uniform probability
plot.

Subject: RE: [ai-geostats] Very high
value
Have
you looked at the data to see if a log-normal population model is more
appropriate than a normal one? Do the very high values actually belong
in the data set or are they evidence of two different populations (for
instance, "background" and "contamination" or maybe "country rock" and
"ore"?)

Dear list
I am working with a data set that as some very
high values, can you pls help with any suggestions on the capping of the
data for setting up variograms calculations.
Then do the capped data get used for the kriging
process.
Thank you
