Fitting a model‣Now you can plot the averagesemivariance versus average distance <strong>of</strong>the bins onto a graph.‣the empirical semivariogram.‣But the empirical semivariogram values cannot be used directly inthe ק matrix because you might get negative st<strong>and</strong>ard errors for thepredictions;‣instead, you must fit a model to the empirical semivariogram.‣Once the model is fit, you will use the fitted model whendetermining semivariogram values for various distances.104
