I doubt any of these models have had proper V&V.


"Verification and Validation". Especially, since validation is impossible. We already know the IHME model wasn't properly verified by a long shot.

Even with a properly V&V'd model, I've yet to see a model of a complex system that was usable for anything more than comparative studies. Using models of complex systems for absolute predictive outcomes make me laugh.

I spent a decade building models/simulations of complex communications systems and protocols. These are systems that are about as deterministic as you can get, with very little assumption or RAND (random number generation for statistic-based behavior) built into the models. Even then, we wouldn't use them as tools for absolute predictive outcome.

The amount of assumption and RAND in these models based on zero previous data without any way to validate them make them completely useless... even if only utilizing them for comparative outcomes.
