Coregionalization and Cokriging
-
摘要: 描述了協同區域化及協同區域化變量的概念,較詳細地討論了交叉矩及其性質(例如互協方差及互變異函數)。重點討論了協同克立格法(包括協同克立格方程組及協同克立格方差等),給出了根據估計鄰域內金和銀的數據,并應用協同克立格法實例估計一個等估塊段中金的平均含量。Abstract: The concept of coregionalization and coregionalized variable are described. The cross-moments and its properties (such as cross-covariance and cross-variogram) are discussed in more detail. In the view of above analysised, the cokriging (include cokriging systems, cokriging variance and so on) is studied mainly, and the mean grade of gold in a block is estimated. This method makes use of estimated level of Au and Ag in neighborhood.
