How the conditional probability changes as a function of the three probability elements

I recently talked about the causes of model performance degradation, meaning when their prediction quality drops with respect to the moment we trained and deployed our models. In this other post, I proposed a new way of thinking about the causes of model degradation. In that framework, the so-called conditional probability comes out as the global cause.

The conditional probability is, by definition, …
