ToxTools

ToxTools is a Statistical Software for Toxicological Risk Assessment.

Features of ToxTools:

• ToxTools is a complete solution for modeling and testing data from dose-response studies, and for estimating Benchmark Dose Levels (BMD's).

• It provides modern, sophisticated modeling and estimation algorithms for fitting dose response data as part of a state-of-the-art suite of graphical and numeric analysis tools for toxicological risk assessment.

• Availability of all standard dose response models (one-hit, logit, probit, Weibull and more).

• Linear, polynomial and power regression models for continuous outcomes.

• Dose response assessment of simultaneous and hierarchical multiple outcomes.

• Analysis of correlated data using generalized estimating equations (GEE).

• Trend and pairwise tests for binary or continuous outcomes.

• Exact tests of trend for both uncorrelated and correlated outcomes in small data sets.

• Single and multiple outcome risk estimation using Benchmark Dose methodology, with several methods for lower limit calculations.

• Simple dialogs for model specification, intelligent recall to modify previous runs and check sensitivity to modeling assumptions.

• Data summarization and exploratory graphics, tailored to the analysis of dose response data. Workbook-style interface for organization and comparison of results.

• Publication quality graphics. Powerful, Excel-like data editor with variable creation, transformation, and case subsetting.
