Abstract
The calibration and enhancement of Wolfe's NORMIX (normal mixtures) computer program in the National Computing Center of the U.S. Environmental Protection Agency at the Research Triangle Park, NC is documented. The program is available for data clustering, validation, and classification. In Part 4, tabular and graphical displays record some aspects of the separation of environmental data into clusters by the NORMIX program. Three CHAMP monitoring sites are principal data sources.
