Does there exist a Penalized Conditional Expectation?

This is a bit different and doesn't address the question, but hopefully close enough to be useful: we know some things about $\mathbb{E} L(Z,Y)$ for other loss functions $L$. If and only if $L$ is a …

Example of a (strictly) proper scoring rule on a general measurable space?

Well, it might be important to limit $\mathcal{P}$ here. If we consider the space $\Omega = \mathbb{R}$ with Lebesgue measure, we might take $\mathcal{P}$ to be the set of distributions with a continu …

Example of a (strictly) proper scoring rule on a general measurable space?

Turns out that Gneiting and Raftery give an example in Section 4.2 of the continuous ranked probability score (CRPS), which is strictly proper for $\mathcal{P}$ equal to the Borel probability measures …
