Dear Raimon, If the data are not spatially correlated, your variogram will be modeled as a pure nugget effect and all observations will receive the same weights in your block kriging estimation. If you perform a global block kriging (i.e. use of a single search window), your estimate will then be the arithmetical average of your observations and the standard error will be provided by the kriging standard deviation.

I'd like to ask to the list, what kind of estimation of reserves should be done in this case? In the absence of spatial dependence, classical statistics should apply: therefore, shall we estimate the mean value of ore content in the "deposit" by the arithmetic mean of the samples? And attach an error to it, in the fashion of the standard error of the mean (something like the variance of the sample divided by number of data used)? Or did I grossly misunderstand something in the discussion, with so much bogus-hocus-pocus and 5-line sentences? thanks for the patience Raimon Tolosana En/na JW ha escrit: > > Hello Readers, > > > > More talk and not test.
