A comparison of search strategies to design the cokriging neighborhood for predicting coregionalized variables

Madani, Nasser; Emery, Xavier (Stochastic Environmental Research and Risk Assessment, 2018-07-06)

Cokriging allows predicting coregionalized variables from sampling information, by considering their spatial joint depen- dence structure. When secondary covariates are available exhaustively, solving the cokriging equations ...
Sequential co-simulation for resources modelling: How good is the reproduction of the joint spatial correlation structure?

Madani, Nasser; Emery, Xavier (The Southern African Institute of Mining and Metallurgy, 2018-08)

The quantification and classification of mineral resources and ore reserves is often based on an assessment of the certainty (or uncertainty) of the estimates of tonnage and grade of elements of interest (metals and ...
