Abstract
Tulisan ini membahas efektivitas penggunaan data berdasarkan estimasi Jackknife-kriging menggunakan simulasi pelenyapan sampel datapadasatu kawasan vein tambang emas.Estimasi berdasarkan sepuluh, dua puluh,tiga puluhdan empat puluhpersen pelenyapan dataawal menggunakanleave one out.Kualitas perhitung dinilai berdasarkan beberapa ralatdan homogenitas distribusi merujuk kepada koefisien variasi.Berdasarkan perhitungan didapat bahwa, estimasi mengacusepuluh dan dua puluh persen pelenyapan data masih cukup efektif digunakan. Kata kunci: Sampel data, emas vein, kriging Jackknife, pelenyapan data, ralat his paper discusses the effectiveness of data based on Jackknife-kriging estimationusing simulation of gold data sampling in vein region.The estimationsbased on ten, twenty, thirty and forty percent of leave-one-out of initial loosing data. The qualityjudged by some errors and also the homogeneity of the distribution refers to the coefficient of variation. Based on the calculations, it is found that the estimationreferring to ten and twenty percent of data elimination are still quite effective.Keywords: Data sample, gold-vein, Jackknifekriging, losing data, error
