标准摘要
[中文适用范围]: 分布的异质性用分布方差来表征,并通过实验测量采样方差来确定。 由于成分方差和分布方差都会对测量的抽样方差产生影响,因此有必要将这两个分量分开。 允许使用两种数据分析方法:使用经典统计的维斯曼抽样理论和变差函数方法,该方法由于考虑了相邻增量之间的序列相关性而给出了更好的估计。 [外文原描述]: The heterogeneity of distribution is characterized by the distribution variance and is determined by experimentally measuring the sampling variance. Because both the composition variance and distribution variance contribute to the measured sampling variance, it is necessary to separate these two components. Two methods of data analysis are permitted: Visman's theory of sampling which uses classical statistics and the variogram method which gives a better estimate because of taking into account serial correlation between adjacent increments.
