"...ToxTools may provide one of the most accessible set of tools for deriving risk estimates for clustered toxicology data."
John Bailer"ToxTools is unique in having a wide range of models, including GEE- based developmental toxicity models and joint outcome models. The model explanations in the manual are complete, and the on-line help is very useful. The interface is intuitive, consistent, and quickly learned."
Mark J. Nicolich"This is a great software package for designing and analyzing toxicological experiments. What previously took quite some time to program myself is now readily available in ToxTools."
