4. Set the Order of Trend Removal to the desired order, then click Next.
5. Specify the desired parameters on the next dialog box and click Next.
6. Specify the desired parameters on the Semivariogram/Covariance Modeling dialog box and click Next.
7. Specify the desired parameters on the Searching Neighborhood dialog box and click Next.
8. Examine the results on the Cross Validation dialog box and click Finish.
