Figure 4From: Sequential interim analyses of survival data in DNA microarray experimentsSimulated FDR ( τ = 50%). The simulated FDR is plotted at each interim analysis in the setting where 50% of all genes were altered between both groups. (a) M = 4 analyses (3 interim and 1 final), (b) M = 10 analyses. The dashed line marks the pre-specified FDR-level of 5%.Back to article page
