Prior-free validity-first optimality of the IM/Hsu interval
Let denote the mean contrast and let denote the variance ratio in the Behrens--Fisher problem. Consider prior-free procedures that are exactly and uniformly valid for…

Finite-sample efficiency conjecture for profile versus extension marginalization
Profile-over-extension efficiency conjecture. Profile-based marginalization is more efficient than extension-based marginalization in finite samples.

Weaker-conditions conjecture for normalized-likelihood possibilistic inferential models
Normalized-likelihood conjecture. The possibilistic IM based on the normalized likelihood should have the same large-sample properties as the IM in Theorem, but under weaker condit…

Asymptotic efficiency conjecture for possibilistic inferential models
Asymptotic efficiency conjecture. Despite the imprecision inherent in an IM, which is necessary to achieve exact validity, there is no loss of efficiency asymptotically.

The incompatibility of behavioral coherence, validity and efficiency in inferential models
An inferential model (IM) produces a coherent lower and upper probability and has strong validity, meaning that its plausibility contour is stochastically no smaller than uniform u…

The incompatibility of strong validity and the likelihood principle for inferential models
An inferential model (IM) is constructed from a statistical model with parameter and sampling distribution ; its plausibility contour is driven by th…

Conjecture that uniformly valid probabilistic predictors are consonant
A probabilistic predictor is a rule assigning predictive probabilities to subsets of possible values of , and its plausibility contour is the function defined by the sourc…
