Even keeping well-understood models up-to-date with changing reality is a hard problem: both labor-intensive & hard to verify.

- catnaroek 11y agoThis depends on the number of degrees of freedom of your model - the dimension of its parameter space. This is why we have tools like https://en.wikipedia.org/wiki/Tornado_diagram https://en.wikipedia.org/wiki/Tornado_diagram and https://en.wikipedia.org/wiki/Analysis_of_variance https://en.wikipedia.org/wiki/Analysis_of_variance: to keep the model's size under control, while still allowing for adjustments to its parameters in the future.
