We design a family of mechanisms with a scoring function that maps a pair of reports to a score. ...
Peer prediction mechanisms incentivize agents to truthfully report their signals even in the absence of verification by comparing agents' reports with those of their peers. ...

We demonstrate that basing the uncertainties on the variability of the bias-corrected point estimator provides significantly improved coverage with only a modest increase in the length of the confidence ...
The first approach applies to situations where the unfolded spectrum is expected to be a smooth function and consists in using an iterative bias-correction technique for debiasing the unfolded point estimator ...
The decision-theoretic justification for the MAP estimator is that it arises as the limit of decisions minimizing the posterior expected loss for the 0-1 loss function where l (β; y) = log p(y|β) is the ...
