摘要: A method for obtaining pointwise or spatially averaged estimates of a nonintrinsic function is introduced based on residual kriging. The relies stepwise iterative regression process simultaneously estimating the global drift and semivariogram. Estimates are then obtained by solving modified set simple kriging equations written residuals. modification consists replacing true variogram in as from process. illustrated considering groundwater levels an Arizona aquifer. results compared with those aquifer generalized covariance package BLUEPACK-3D.
