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.
