and time flexibility, as well as many estimation routines for missing data. The latter
also make it very complex and opaque. Furthermore, any form of data exchange with
other applications is very difficult, if not impossible, including uncertainty and sensi-
bility analysis. With EUSES, not as many substances can be assessed as with CalTOX.
To make the choice of model easier, the user needs to know the desired results,
the substances to be evaluated, and to which situation to apply the model. As the
following comparison of the two models shows, each gives different results and fits
