对我国进口铁矿石中的环境有害元素As、Cr、Cd、Pb、S的含量进行了总体统计分析，选用了四分位稳健统计分析及内核密度估计分别对铁矿中的有害元素As、Cr、Cd、Pb、S的含量的代表值进行估计，探讨了两种方法在代表值估计方面的特点，并使用主成分分析、因子分析等多元统计分析方法对有害元素的含量特征进行整体分类描述，确定了含量特征整体分类的主要有害元素，全面了解进口铁矿中涉及安全、环保等有害元素的质量状况。

It is interpreted that the correlation structure of the allelic polymorphism data contains null correlations introduced by "closure" and the statistical distribution of the data is not normal because of its constant row sum,which resulted in great difficulties in analyzing the data with traditional multiple linear statistical methods such as principal component analysis,factor analysis,cluster analysis and canonical correlation analysis.

长期以来，对于多维基因多态性数据的多元统计分析，如计算遗传距离时所用的聚类分析、分析群体遗传结构时所用的主成分分析、因子分析和典型相关分析等，一直应用为无约束条件数据而设计的经典多元线性分析方法，并没有注意基因多态性数据的"闭合效应"所带来的问题。
