Overview of our family of groundwater and environmental statistics programs: DUMPStat, Explorer and CARStat.
DUMPStat is a powerful statistics package
for detection monitoring data analysis and management at landfills
and industrial facilities.
MIXOR, MIXREG, MIXNO and MIXPREG provide estimates
for mixed-effects ordinal probit and logistic regression model, mixed-effects
regression models (MRM) including autocorrelated errors, mixed-effects
nominal logistic regression analysis, and mixed-effects Poisson regression
DUMPStat Explorer is a suite of evaluation
tools for exploring site data, comparing chemical signatures, and
investigating hydrogeological samples. Explorer generates Stiff
Patterns, Trilinear Diagrams, Multi-Line Time Series, and XY Scatter
Plots; and features live editing capabilities for quick results.
Detect can compute both detection and quantification
limits from either single concentration data or calibration based
data (i.e. multiple concentrations).
CARStat extends DUMPStat's capabilities
with statistics specific to compliance, assessment, and remediation.
CARStat and DUMPStat are based on the work of Dr. Robert D. Gibbons.
