Weighted jackknife ordinary kriging - problem solution of the precision in mineral resources estimation

open access: diamondIOP Conference Series: Earth and Environment, 2018
The aim of introducing the weighted jackknife ordinary kriging (WJOK), as a robust estimator, is to solve the outliers and the problems of uncertainty associated with grade estimates of mineral resources.

Ordinary kriging dalam penentuan lama penggalian tambang terbuka

open access: yesTeknika, 2019
Perkiraan sisa cadangan di PT. Allied Indo Coal Jaya belum dapat dipastikan, karena perhitungan cadangan mengacu pada hasil pemboran eksplorasi yang cukup lama yaitu pada tahun 2008, sehingga perlu adanya evaluasi perhitungan cadangan ulang yang tersedia.

Geostatistics for functional data: an ordinary kriging approach

open access: gold, 2007
We present a methodology to perform spatial prediction when measured data are curves. In particular, we propose both an estimator of the spatial correlation and a functional kriging predictor. We adapt an optimization criterium used in multi- variable spatial prediction in order to estimate the kriging parameters.
