SENSITIVITY ANALYSIS IN SPATIAL STATISTICS: DETECTING INFLUENTIAL OBSERVATIONS IN SPATIAL PREDICTION

An important problem in spatial statistics is to predict the unobserved value z(s0) at a specified location s0 based on the information of n observations z(sα), α=1, …, n. It can be achieved in three stages of (1) estimating the variograms, (2) fitting a model to the estimated variograms, and (3) ap...
