Abstract
Kriging is a construction method that is primarily built based on the structure of experimental semivariograms and the power of fitting. The two functions, i.e., classical and robust semivariograms, are used in the current study. The emivariograms are fitted using two approaches, namely, ordinary least squares and weighted least squares, whereas the spherical and exponential functions are utilized for the theoretical model. The estimation precision is calculated using the root mean square error. The error use of the root mean squares for predictions was tested using the mean absolute deviation. Keywords: semivariogram, OLS and WLS fitting, ordinary kriging.
