Cokriging模型
WebSeveral packages are available in R to conduct interpolation by kriging, including “kriging” (simple package covering ordinary kriging), “gstat” (enables many forms of kriging including ordinary, universal, block, etc.), “geoR” and “geoRglm” (for Bayesian kriging). Below are some resources that pertain to the “kriging” and ... Whether by hand or by computer, contouring data requires the use of an interpolation procedure. Many algorithms are used … See more So far the discussion on cokriging has covered the geostatistical techniques available for data integration when a correlation exists between two or more attributes. Three factors are important for effective data … See more Tables 1 and 2 summarize key aspects, benefits, and limitations of kriging and cokriging. 1. Table 1—Kriging Summary 2.

Web(4)Cokriging模型是通过加入样本点处的一阶导数信息来对Kriging进行的改进来提高代理模型的精度的。二阶导数信息也同样可以用于提高代理模型的精度。因此提出了Hessian-enhanced Kriging模型,并将其应用于可靠度分析中,并通过算例验证其对可靠度分析的有效性。 Web不同的克里金模型. 需要 Geostatistical Analyst 许可。 克里金方法依赖于数学模型和统计模型。通过添加包含概率的统计模型，可将克里金方法从空间插值的确定性方法中描述的确定性方法中分离出来。 对于克里金法，您会将某种概率与预测值相关联；也就是说，这些值不能完全基于统计模型进行预测。
WebThe cokriging estimator is written as: The corresponding cokriging system requires knowledge of only the Z covariance C Z ( h) and the Z − Y cross-covariance C Z Y ( h). The latter can be approximated through the following model: where B = C Y ( 0) / C Z ( 0) ⋅ ρ Z Y ( 0), C Z ( 0), C Y ( 0) are the variances of Z and Y, and ρ Z Y ( 0) is ...
