Description

ChemStat stands out as the most user-friendly and rapid solution for performing statistical evaluations on groundwater monitoring data at RCRA facilities. This application encompasses a wide range of statistical techniques outlined in the 1989 and 1992 USEPA statistical analysis documents, the USEPA Draft Unified Guidance Document, the U.S. Navy Statistical Analysis Guidance document, along with various other recognized guidance and methodologies from esteemed statistical literature. Its remarkable blend of simplicity and cutting-edge technology positions ChemStat as the leading choice for environmental statistical analysis. The constraints on data set size are primarily determined by the computer's memory for the majority of tests, allowing for an extensive array of parameters, wells, and sample dates. Additionally, users can enjoy the flexibility of having limitless parameter names and well label lengths, and they can easily exclude specific data points from their analyses, enhancing the application’s versatility even further. This makes ChemStat an invaluable tool for professionals dealing with complex environmental data.

Description

NLREG is an advanced statistical analysis tool designed for both linear and nonlinear regression analysis, as well as for fitting curves and surfaces. It identifies the optimal values of parameters for a user-defined equation, ensuring that it best aligns with a given set of data points. Capable of managing various function types, including linear, polynomial, exponential, logistic, periodic, and more general nonlinear forms, NLREG stands out because it can accommodate nearly any algebraically specified function. Unlike many other nonlinear regression tools that are restricted to a limited selection of functions, NLREG offers a comprehensive range of possibilities. The program incorporates a robust programming language with a syntax akin to C, allowing users to define the function to be fitted while enabling the computation of intermediate variables, the use of conditionals, and the implementation of iterative loops. Furthermore, NLREG simplifies the creation of piecewise functions that can adapt their form across different ranges. Additionally, the inclusion of arrays in the NLREG language facilitates the use of tabular lookup methods to designate the function, providing even greater flexibility for users in their analyses. Overall, NLREG is an invaluable asset for statisticians and data analysts seeking to conduct complex fitting tasks.
