# Bayesian heavy-tailed models and conflict resolution: A review

@article{OHagan2012BayesianHM, title={Bayesian heavy-tailed models and conflict resolution: A review}, author={Anthony O'Hagan and Luis Ra{\'u}l Pericchi}, journal={Brazilian Journal of Probability and Statistics}, year={2012}, volume={26}, pages={372-401} }

We review a substantial literature, spanning 50 years, concerning the resolution of conicts using Bayesian heavy-tailed models. Conicts arise when di¤erent sources of information about the model parameters (e.g. prior information, or the information in individual observations) suggest quite di¤erent plausible regions for those parameters. Traditional Bayesian models based on normal distributions or other conjugate structures typically resolve conicts by centring the posterior at some…

Robustness against conflicting prior information in regression

- Mathematics
- 2021

Including prior information about model parameters is a fundamental step of any Bayesian statistical analysis. It is viewed positively by some as it allows, among others, to quantitatively…

BAYESIAN ROBUSTNESS MODELLING USING THE FLOOR DISTRIBUTION

• In Bayesian analysis, the prior distribution and the likelihood can conflict, in the sense that they can carry diverse information about the parameter of interest. The most common form of conflict…

Bayesian robustness modelling using the O‐regularly varying distributions

- Computer Science, Mathematics
- 2017

This work proposes a robustness modelling approach based on the O‐regularly varying class (ORV), which is a generalization of the regular variation family; however, the ORV class allows more flexible tails behaviour, which can improve the way in which the outlying information is discarded by the model.

Robust Bayesian Regression Analysis Using Ramsay-Novick Distributed Errors with Student-t Prior

This paper investigates bayesian treatment of regression modelling with Ramsay - Novick (RN) distribution specifically developed for robust inferential procedures. It falls into the category of…

Default Bayesian Analysis with Global-Local Shrinkage Priors

- Computer Science
- 2015

The horseshoe priors, originally designed to handle sparsity, also possess regular variation and thus are appropriate for default Bayesian analysis, and are found to separate a low-dimensional signal embedded in high-dimensional noise, even for nonlinear functions.

Bayesian Restricted Likelihood Methods

- Computer Science
- 2014

Using several ii data analyses, the benefits of the new approach over the traditional approaches is made apparent and these benefits often manifest themselves through more realistic assumptions and more precise predictive performance.

A New Bayesian Approach to Robustness Against Outliers in Linear Regression

- Computer Science
- 2016

This paper proposes a model with super heavy-tailed errors, and proves that it is wholly robust, meaning that the impact of outliers gradually vanishes as they move further and further away form the general trend.

Robust Bayesian Reliability for Complex Systems under Prior-Data Conflict

- Computer ScienceASCE-ASME Journal of Risk and Uncertainty in Engineering Systems, Part A: Civil Engineering
- 2018

An approach to mitigate prior-data conflict is presented, by considering sets of prior distributions to model limited knowledge on Weibull distributed component lifetimes, treating systems with arbitrary layout using the survival signature.

A Proposal for Informative Default Priors Scaled by the Standard Error of Estimates

- MathematicsThe American Statistician

Abstract If we have an unbiased estimate of some parameter of interest, then its absolute value is positively biased for the absolute value of the parameter. This bias is large when the…

Bayesian robustness modeling using regularly varying distributions

Bayesian robustness modelling using heavy-tailed distributions provides a flexible approach to resolving problems of conflicts between the data and prior distributions. See Dawid (1973) and O’Hagan…

Conflicting information and location parameter inference

- Mathematics
- 2007

It is shown that the posterior distribution converges in law to a density proportional to the product of the densities of the non-conflicting information, as the outliers (and/or the prior location) go to plus or minus infinity, at any given rate.

Abstract. The modelling process in Bayesian Statistics constitutes the fundamental stage of the analysis, since depending on the chosen probability laws the inferences may vary considerably. This is…

Abstract Heavy-tailed distributions are important for modeling problems in which there may be outlying observations or parameters. Examples of their use are given in O'Hagan (1988). This article…
