Handling measurement error when modeling semivariogram and covariance functions

Etapes :

1. Start the Geostatistical Analyst Wizard , choose a kriging method, then begin to construct your model.

   For an example on how to start constructing a kriging model, refer to Using ordinary kriging to create a prediction map.

2. When you reach the Semivariogram/Covariance Modeling page, enter a value for the Measurement Error parameter.

   The value can be entered as a percentage of the Nugget or as a numeric value (which has to be less than or equal to the Nugget value).

Astuce:

If you have multiple measurements per location (coincident data), let Geostatistical Analyst compute the measurement error for you by selecting Estimate value from the drop-down list.

Remarque :

If the measurement error is set to zero, you'll get "exact" kriging.
