Abstract
This study examines the relationship between the results of semivariogram fitting conformity with estimating based on errors produced. The experimental semivariogram estimation was calculated using robust methods, while the theoretical semivariogram function used are spherical and exponential models, with weighted least squares and ordinary least squares approaches. Consistently, the four semivariogram fittings produce root mean square error (RMSE) fluctuates, while the values are proportionally to the median absolute deviation (MAD) generated by ordinary kriging. Keywords: robust semivariogram, WLS and OLS, ordinary kriging
