credibility.risk¶

The model risk, the default acceptances and the default minimum of points.

The model risk follows ICH M15 and V&V 40 as a lookup of the influence of the model on the decision and the consequence of a wrong decision. It is a table and not a formula, so it can be changed in one place. The rules of an evidence extension, e.g. of the ratio pairs, have their defaults in the extension, see sbmlsim.credibility.extensions.
