[ai-geostats] XValid script
It may be cheeky, but I have two questions:
1. Where can I get I get the Surfer v7.0 script for crossvalidation? I
have been through the archives and although its mentioned I cannot find
a download site. Nor could I find it and the site of Aleksey Amantov.
Some emails mentioned it is in the samples folder of the surfer install
but I could not find it. I know its in Surfer 8 as standard but thats
not available to me at the moment.
2. I have been following the discussion on extreme values in a data set.
And my question is: is there any context in which geostatistical methods
are absolutely not appropriate? If so, how can this appropriateness be
tested? Is there a point at which a user should know that it would be
better to try something else?
Any help with these two is very much welcome
