GEOSTATS: Minimum Curvature and Cross Validation
Minimum curvature is an iterative interpolation process which minimizes residuals of a Generalized
Cross Validation. It repeats the interpolation process until all points in the data have a
residual less than the maximum residual setting.
I'm assuming this is how Surfer 6.0 performs its minimum curvature (please let me know if I'm
The question: Is it reasonable to perform a cross validation (independent of the one that is done
automatically) on a grid created by minimum curvature? Are the results of the cross validation
