因子克立格分析的理论研究及应用展望

THE THEORY STUDY AND APPLICATION PROSPECT OF FACTORIAL KRIGING ANALYSIS

本文介绍了区域化变量的分解和估值的理论及发展,在说明了区域化现象中应用因子克立格分析的重要性后,阐述了单变量和多变量因子克立格分析的理论和方法,并给出了应用实例。多变量的情形有两种模型,分别来自方差—协方差阵和协区域化矩阵的主成分分解。后一种模型中还增加了区域化因子的概念,本文最后对该理论和方法的研究成果及应用前景作了评估。

The paper introduces the theory and its development of the factorial Kriging analysis. It lays stress on the importance of the methods in application of the coregionalization phenomenon, and points out the factorial Kriging system of univariate and multivariate data and gives some application cases. In the case of multivariate theory, two models are obtained, which have been derived from the decomposition of variance - covariance matrix and coregionalization matrix, respectively. Finally, the research achievements and application prospect of the methods are discussed.
