Bayesian Decision Theory for Multiple Comparisons Charles Lewis Fordham University Educational Testing Service Abstract
A loss function related to the
directional false discovery rate (DFDR) criterion for evaluating
multiple comparisons procedures is introduced. The Bayes decision
rule for this loss is obtained. When used with a vague prior,
this Bayes rule is shown to be very similar to the sampling theory
procedure introduced by Benjamini and Hochberg to control the
FDR. This provides a new perspective on the properties of
FDR-controlling procedures.
