When directional forecasting is found empirically successful, it is tempting to assert that it is driven by (perhaps subtle) nonlinear conditional mean dependence, which would be missed in standard analyses of (linear) dependence, such as t ...

Hence, in evaluating the procedure, we should simultaneously be averaging over the differing means and data. This is in contrast to text ...

For instance, there could be no way to reliably infer any causal conclusions whatever from probabilistic relations grounded upon statistics, in the form of the Criterion, or any other f ...

A second reason is that often we are unable to say anything at all about the expectation of an estimator. The expected value rules are weak analytical instruments t ...

... support is contained in Ka (r, m). In many cases of interest, we can think of PRa (r, m) as arising from conditioning an initial probability on runs on the agent’s current local state, to give a probability on points. There are subtleties to doing this though. We often do not have a probability on t ...

Codensity and the Giry monad
... The codensity monad of U : C = {I 0 , I 1 , I 2 , . . .} → Meas is the finitely additive Giry monad F. The codensity monad of V : D = {I 0 , I 1 , . . . , d0 } → Meas is the Giry monad G. Sketch proof: The forgetful functor Meas → Set is representable. Hence for Ω ∈ Meas, the underlying set of T U Ω ...
