hello list, you can see the paper here (hope the link works): http://www.uni-hohenheim.de/~kuzyakov/I-EaSS1b.pdf look at page 3 (1221) here they describe the trend removal in the variogram regards Lenz -- * To post a message to the list, send it to [EMAIL PROTECTED] * As a general service to the users, please remember to post a summary of any useful responses to your questions. * To unsubscribe, send an email to [EMAIL PROTECTED] with no subject and "unsubscribe ai-geostats" followed by "end" on the next line in the message body.

Re: AI-GEOSTATS: Question about Block Lognormal Kriging.
Adrian I don't do simple kriging, but both forms of the complete backtransform are available in the papers presented at Geocongress 1998 and Pribram 1999. These are available at http://uk.geocities.com/drisobelclark/resume/Publications.html If you have any problems downloading, let me know.
