Interactive Use of Computer Drawn Faces to Study Multidimensional Data.

摘要

The interactive use of computer-drawn faces to examine multidimensional data is demonstrated. The code, DRFACE,allows the user to view facial representations of data at a graphics terminal and then,by easily made changes,to display new representations of the same data. The user can change the facial feature/data variable assignments,the facial feature ranges,and default values. This ability permits the user to determine if observations made about the data from viewing the first set of faces are due to chance assignments or actually reflect patterns in the data. 8figures, 5tables.
