Frameworks for prior-free posterior probabilistic inference

*Wiley Interdisciplinary Reviews: Computational Statistics*, *7*(1), 77–85.

author keywords: Bayes; belief function; fiducial; inferential models; statistical principles

TL;DR:
It is argued that Fisher's fiducial and its various extensions are not prior-free and, therefore, do not meet the requirements for prior‐free probabilistic inference, and the inferential model (IM) framework is shown to be a promising new method for generating both valid and efficient probabilism inference.

Marginal Inferential Models: Prior-Free Probabilistic Inference on Interest Parameters

*Journal of the American Statistical Association*, *110*(512), 1621–1631.

author keywords: Belief; Efficiency; Nuisance parameter; Plausibility; Predictive random set; Validity

TL;DR:
It is shown that this approach provides exact and efficient marginal inference in several challenging problems, including a many-normal-means problem, and a generalized marginalization technique is proposed and proved its validity.

Plausibility Functions and Exact Frequentist Inference

*Journal of the American Statistical Association*, *110*(512), 1552–1561.

author keywords: Bootstrap; Confidence region; Hypothesis test; Likelihood; Monte Carlo; p-Value; Profile likelihood

TL;DR:
This article presents a general framework for the construction of exact frequentist procedures based on plausibility functions and shows that the plausibility function-based tests and confidence regions have the desired frequentist properties in finite samples.

Random Sets and Exact Confidence Regions

*Sankhya A*, *76*(2), 288–304.

author keywords: Coverage probability; inferential model; plausibility function; predictive random set; validity

TL;DR:
This paper describes a new approach, using random sets, which allows users to construct exact confidence regions without appeal to asymptotic theory, if the user-specified random set satisfies a certain validity property.

An Approximate Bayesian Marginal Likelihood Approach for Estimating Finite Mixtures

*Communications in Statistics - Simulation and Computation*, *42*(7), 1533–1548.

author keywords: Dirichlet distribution; Mixture complexity; Predictive recursion; Simulated annealing; Stochastic approximation

TL;DR:
A computationally efficient stochastic approximation version of the marginal likelihood is proposed and large-sample theory is presented by restricting the support to a finite grid, and a simulated annealing method is employed to maximize themarginal likelihood and estimate the support.

Inferential Models: A Framework for Prior-Free Posterior Probabilistic Inference

*Journal of the American Statistical Association*, *108*(501), 301–313.

author keywords: Belief function; Plausibility function; Predictive random set; Score function; Validity

TL;DR:
A new framework for probabilistic inference, based on inferential models (IMs), is presented, which not only provides data-dependent Probabilistic measures of uncertainty about the unknown parameter, but also does so with an automatic long-run frequency-calibration property.
