STATISTICAL SOFTWARE PROUCL 5.1.00 FOR ENVIRONMENTAL APPLICATIONS FOR DATA SETS WITH AND WITHOUT NONDETECT OBSERVATIONS
U.S. EPA Software Download, 2020

ProUCL version 5.1.002 (5.1) is the latest update of the ProUCL statistical software package for analysis of environmental data sets with and without non-detect (ND) observations. ProUCL version 5.1 is a comprehensive statistical software package with statistical methods and graphical tools to address many environmental sampling and statistical issues. In ProUCL 5.1, some enhancements have been made in the Trend Analysis option of the Statistical Test module. ProUCL 5.1 computes and outputs residuals for the non-parametric T-S trend line which may be helpful to compute a prediction band around the T-S trend line. In addition to generating Q-Q plots based upon detected observations, the Goodness of Fit Tests option of the Statistical Tests module of ProUCL 5.1 generates censored probability plots for data sets with NDs. Some changes have been made in the decision table used to make suggestions for UCL selection based upon a gamma distribution. https://www.epa.gov/land-research/proucl-software
