Annotation

Environmental Stats for S-Plus is an add-on module to S-Plus and the first comprehensive software package for environmental scientists, engineers, and regulators. Environmental Stats for S-Plus provides a set of powerful, simple-to-use, pull-down menus and functions for performing graphical and statistical analyses of environmental data, parameter and quantile estimation, methods for dealing with nondetects, power and sample-size calculations, prediction and tolerance intervals, and probabilistic risk assessment. Environmental Stats for S-Plus includes and extensive hypertext help system that explains methods from the environmental literature and regulatory guidance documents, along with a glossary of commonly used statistical and environmental terms. This new edition of the Users Manual provides the documentation for Version 2.0 (which runs under S-Plus 6.0), and includes extensive examples using data sets from regulatory guidance documents. All examples show how to produce the results by using the new pull-down menus or by calling functions from the command line.
