论文摘要
柯林斯（Collins）（2002）的陈述“通讯分析使您失明”之后，他的序列化如Whitlark和Smith（2001）分析的品牌属性计数数据集，后者应用了通信分析。在本文中，我们通过同时分解协方差矩阵及其关联的密度矩阵，对Collins在Taxicab对应分析框架中的陈述进行评论，从而解释了两个相互关联的图表：TCOV映射和TCA映射。
Collins' (2002) statement "correspondence analysis makes you blind" followed after his seriation like description of a brand attribute count data set analyzed by Whitlark and Smith (2001), who applied correspondence analysis. In this essay we comment on Collins' statement within taxicab correspondence analysis framework by simultaneously decomposing the covariance matrix and its associated density matrix, thus interpreting two interrelated maps for contingency tables : TCov map and TCA map.
