In science:

Again, the goal is to find the minimum sample size per null in order to attain a given pFDR level, in particular when Fi under false Hi only have small differences from those under true Hi .
Sample size and positive false discovery rate control for multiple testing
Under the random effects model (1.1), each null Hi is associated with a distribution Fi , such that when Hi is true, Fi = P0 , and when Hi is false, Fi = Pθ , where θ > 0 is a constant.
Sample size and positive false discovery rate control for multiple testing
Assume that each Hi is tested based on an iid sample {ωij } from Fi , such that the samples for different Hi are independent, and the sample size is the same for all Hi .

Renormalization theory for multimodal maps
Since Hi is increasing, it suffice to show that if fi−1 (ci−1 ) is the j -th point in Ai , with respect to the order in the real line, then ˜fi−1 (˜ci−1 ) is also the j -th point in ˜Ai .
