Sample Size Growth with an Increasing Number of Comparisons

Figure 4

Sample size versus log𝑀 (base 10) for controlling FDR 𝑓=5% with Ψ=90%. The open circles represent the sample sizes needed when the number of true alternatives 𝑚₁ stays as constant (𝑚₁=40), the plus signs give the sample sizes when 𝑚₁=2log𝑀, and the triangles are the sample sizes when the proportion of true alternatives is constant (𝑚₁=𝑀/10).
