Using history matching for prior choice

Xueou, Wang, Nott, David J., Drovandi, Christopher C., Mengersen, Kerrie, & Evans, Michael (2016) Using history matching for prior choice. [Working Paper] (Unpublished)



It can be important in Bayesian analyses of complex models to construct informative prior distributions which reflect knowledge external to the data at hand. Nevertheless, how much prior information an analyst is able to use in constructing a prior distribution will be limited for practical reasons, with checks for model adequacy and prior-data conflict an essential part of the justification for the finally chosen prior and model. This paper develops effective numerical methods for exploring reasonable choices of a prior distribution from a parametric class, when prior information is specified in the form of some limited constraints on prior predictive distributions, and where these prior predictive distributions are analytically intractable. The methods developed may be thought of as a novel application of the ideas of history matching, a technique developed in the literature on assessment of computer models. We illustrate the approach in the context of logistic regression and sparse signal shrinkage prior distributions for high-dimensional linear models.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
