Using disjunctive kriging to create a prediction standard error map
A standard error map quantifies the uncertainty of the prediction. If the data comes from a normal distribution, the true value will be within ± 2 times the prediction standard errors approximately 95 percent of the time.
Schritte:
- Start the Geostatistical Analyst Wizard .
- Select Kriging/CoKriging, choose a dataset and attribute field, then click Next.
- Choose Disjunctive, set the Transformation type to Normal Score, set the Output Type to Prediction Standard Error, then click Next.
- Specify the desired parameters on the Normal Score Transformation dialog box and click Next.
- Specify the desired parameters on the Semivariogram/Covariance Modeling dialog box and click Next.
- Specify the desired parameters on the Searching Neighborhood dialog box and click Next.
- Examine the results on the Cross Validation dialog box and click Finish.
- Click OK on the Method Report dialog box.
