2007 External Review of the Multistage Weibull Time-to-Tumor Model

In June, 2007, a new time-to-tumor multistage Weibull model ("MSW") was externally reviewed by experts, with reviews generally positive and confirmed that the functioning of the computer code had been rigorously tested.

The reviewers' comments are provided with EPA's responses (finalized in 2008, after revisions to the program and documentation that were followed by more testing).
