Re: [ai-geostats] Very high value
MessageIt is also worthwhile to look at a log-uniform probability plot.----- Original Message -----From: Glover, TimSent: Tuesday, October 11, 2005 8:51 AMSubject: RE: [ai-geostats] Very high valueHave 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"?)

Subject: [ai-geostats] Very high value
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.
