Yes, exactly -- this is what validation means in the context of physiological models (and economic models, too). But some validation (call it confirmation if it makes you happier) is certainly required -- and an important part of the release of the model is to indicate exactly what situations the model was validated in. Without this information, we risk applying a model to situations in which it makes highly precise, though inaccurate, predicitons -- with nasty consequences for the user. I am wondering specifically the Abyss people will do to prevent this. -frank -- fhd@in*.ne* | [M]athematics is not the study of intangible Platonic 1 212 559 5534 | worlds, but of tangible formal systems which have arisen 1 917 992 2248 | from real human activities. 1 718 746 7061 | -- Saunders MacLane
