Testing over a continuum of null hypotheses with False Discovery Rate control
We consider statistical hypothesis testing simultaneously over a fairly general, possibly uncountably infinite, set of null hypotheses, under the assumption that a suitable single test (and corresponding $p$-value) is known for each individual hypothesis. We extend to this setting the notion of false discovery rate (FDR) as a measure of type I error. Our main result studies specific procedures based on the observation of the $p$-value process. Control of the FDR at a nominal level is ensured either under arbitrary dependence of $p$-values, or under the assumption that the finite dimensional distributions of the $p$-value process have positive correlations of a specific type (weak PRDS). Both cases generalize existing results established in the finite setting. Its interest is demonstrated in several non-parametric examples: testing the mean/signal in a Gaussian white noise model, testing the intensity of a Poisson process and testing the c.d.f. of i.i.d. random variables.

- Supplementary material: Supplement to: “Testing over a continuum of null hypotheses with False Discovery Rate control”. This supplement provides some technical results and introduces the so-called general PRDS condition, which is a stronger assumption than the finite dimensional PRDS condition. This condition is useful to prove FDR control for procedures which are not necessarily of the step-up type.
