ProUCL – A software package developed by the Unites States Environmental Protection Agency. ProUCL is a comprehensive statistical software package with statistical methods and graphical tools to address many environmental sampling and statistical issues. Can be used for the analysis of environmental data sets with and without nondetect (ND) observations.
Scout – An older version of ProUCL and similar in many ways. From the website ” provides a wide variety of classical and robust statistical methods that are not typically available in other commercial software packages. A major part of Scout deals with classical, robust, and resistant univariate and multivariate outlier identification, and robust estimation methods that have been available in the statistical literature over the last three decades.”
VSP (Visual Sample Plan) – Relatively powerful sampling plan generator. from the website “VSP is a software tool that supports the development of a defensible sampling plan based on statistical sampling theory and the statistical analysis of sample results to support confident decision making. VSP couples site, building, and sample location visualization capabilities with optimal sampling design and statistical analysis strategies. VSP is currently focused on design and analysis for the following applications.”
R – a free software environment for statistical computing and graphics. R provides a wide variety of statistical (linear and nonlinear modelling, classical statistical tests, time-series analysis, classification, clustering, …) and graphical techniques. One of R’s strengths is the ease with which well-designed publication-quality plots can be produced, including mathematical symbols and formulae where needed.
MAROS – The Monitoring and Remediation Optimization System is used to make long term site monitoring more effective. Combines optimization and data quality objectives to determine optimum sampling density and frequency. Computes plume stability analyses via Mann Kendall trends.
Practical Statistics – Informative website on common statistical tests for environmental problems. Specific information on how to best handle value below reporting or detection limits.
