From: Lessening the adverse effect of the semivariogram model selection on an interpolative survey using kriging technique

Model Experimental value, R (Ω m) Estimated value \(R^{*}\) (Ω m) \(\frac{{R^{*} - R}}{R}(\% )\) Comments
Gaussian 200 201 +0.5 Almost identical
Exponential 200 132 −34 Underestimated
Magnetic 200 143 −29 Underestimated
Spherical 200 98 −51 Very underestimated
