AI-GEOSTATS: Nugget effect and Surfer 8 (3 and end)
- Good day everyone,
In an previous mail I mentioned a problem I have found in Surfer concerning
the statistics (obtained during the cross-validation step) generated when the
"No search" option was set.
Apparently the bug "caused the gridding search neighborhood to contain more or
less points than it should have"
A patch has been released and users can upgrade Surfer 8 to version 8.03 via
Although the developers present the patch as solving "subtle accuracy errors",
as it was the case in the example I have sent them when explaining the
problem, it may have affected your work in a more serious manner.
PS: more info can be found in the archives of the discussion forums of
AI-GEOSTATS and Surfer as well as in the information about the latest release
of Surfer http://www.goldensoftware.com/surferhistory.shtml
