Hi all, the simple kriging weights do not sum to a constant. >From Olea (1999): 'Geostatistics for engineers and earth scientists', Kluwer, Boston, p.60: '(c) The possibility of having negative weights implies that the estimate is not confined to the data interval;...'
To me, this sounds like if the sum of the simple kriging weights is resticted to some interval, especially since I've never seen any sum of weights not in [0,1]. Does anybody know any hint, evidence or proof of such a restriction? Thanks a lot. --------------------------------- Andreas Dominik Cullmann Institut fuer forstliche Biometrie und Informatik Buesgenweg 4 37077 Goettingen Germany Tel: ++49-551-39-3462
