Bayes-optimal prediction with frequentist coverage control

Hoff, Peter

Understand

This article illustrates how indirect or prior information can be optimally used to construct a prediction region that maintains a target frequentist coverage rate.

  • If the indirect information is accurate, the volume of the prediction region is lower on average than that of other regions with the same coverage rate.
  • Even if the indirect information is inaccurate, the resulting region still maintains the target coverage rate.
  • Such a prediction region can be constructed for models that have a complete sufficient statistic, which includes many widely-used parametric and nonparametric models.
