Calculating the empirical semivariogramthe goal is to solve the equations for all <strong>of</strong>the ג is (the weights), so the predictor canbe formed by usingThe matrix formula for ordinary kriging is:‣The gamma matrix ק contains the modeled semivariogram valuesbetween all pairs <strong>of</strong> sample locations, where ɣ ijdenotes the modeledsemivariogram values based on the distance between the two samplesidentified as the ith <strong>and</strong> jth locations.‣The vector g contains the modeled semivariogram values between eachmeasured location <strong>and</strong> the prediction location, where ɣ i0denotes themodeled semivariogram values based on the distance between the ithsample location <strong>and</strong> the prediction location.103
