Figure 1From: Gene set analysis for longitudinal gene expression dataThe power curve of NP statistic based on the asymptotic distribution compared to LME and GEE. The empirical powers of the NP statistics for testing of no treatment effect based on the asymptotic distribution compared to LME and GEE are given here. The powers were estimated at level 0.05. Δ is the log-scale mean difference between successive treatment groups.Back to article page
