Estimation on Sampling and Analytical Quality in Geochemical Survey for Organic Materials in Soils with Robust ANOVA

摘要: 用稳健方差分析评估地球化学调查土壤中有机质的采样和分析质量,表明稳健方差统计比传统方差统计更能反映地球化学场的真实分布,提出重视深部土壤采样设计方案。

Abstract: Estimation of sampling and analytical quality in geochemistry survey for organic materials in soils with robust ANOVA is reported in this paper. The results show that the estimation results from robust ANOVA much truly reflect the distribution of geochemi
