Focused Bayesian prediction

Abstract: We propose a new method for conducting Bayesian prediction that delivers accurate predictions without correctly specifying the unknown true data generating process. A prior is defined over a class of plausible predictive models. After observing data, we update the prior to a posterior over these models, via a criterion that captures a user-specified measure of predictive accuracy. Under regularity, this update yields posterior concentration onto the element of the predictive class that maximizes the expectatio… Show more

“…Alternatively, non-proper scoring rules could be used which emphasise a particularly important aspect of inference to the task at hand e.g. the tails of the distribution (Loaiza-Maya et al, 2021). Another variation is to allow more freedom to the critic.…”

“…The use of scoring rules for Bayesian updating for parameters was pioneered by Bissiri et al (2016) (rather than inference about models in forecast combination) and is justified in a M-open or misspecified setting. Loaiza-Maya et al (2021) extend this approach to econometric forecasting. They both consider sums which are equally weighted (i.e.…”
