| Abstract |
A method is reported for assessing the degree of separation between two clusters of points representing chemical data. The method, based on trend vectors, has been tested on both randomly generated and actual data sets. The index is intended to be a quick method for detecting the relative degree of separation between data sets (i.e., suitability of descriptors being used) in structure-activity studies or other pattern-recognition studies. |
