Average power for different methods purporting to control the FDR at <i>α</i> = 0.05.

<p><i>A</i> can be thought of as the magnitude of differential abundance for truly differentially abundant features, and <i>ρ</i> is the true correlation within blocks of dependent tests. The blue solid circles represent the case of 120 dependent tests (out of 2000 total), whereas the red solid triangles are for the case of 360 dependent tests. Parentheses indicate ± 2 SEM.
