Facial Representation of Multivariate Data
介绍了Chernoff提出的用卡通人脸图形表示多元数据的方法，包括构建人脸的机制和几何关系，并举例说明该方法如何揭示变量间微妙但重要的关系。
An application of a relatively new method of depicting multivariate data graphically, this article presents a method developed by Chernoff consisting of representing a point in k-dimensional space as a cartoon of a face. The authors briefly describe the mechanics of constructing a face as well as the geometric relationships involved, illustrate the use of faces as a method of portraying multivariate data graphically, and exemplify the use of this method in detecting subtle, yet potentially significant relationships among variables.
