Point and Interval Estimation of Variogram Models Using Spatial Empirical Likelihood
利用空间经验似然进行变差函数模型的点估计与区间估计
We present a spatial blockwise empirical likelihood method for estimating variogram model parameters in the analysis of spatial data on a grid. The method produces point estimators that require no spatial variance estimates to compute, unlike least squares methods for variogram fitting, but are as efficient as the best least squares estimator in large samples. Our approach also produces confidence regions for the variogram, without requiring knowledge of the full joint…
