Fig. 2From: SEMgsa: topology-based pathway enrichment analysis with structural equation modelsAverage type I error on the 10 KEGG pathways grouped by method and mean signal on simulated data. Average type I error together with standard deviation across simulations is displayed for each method. Lower type I error indicates better performance. At the 0.05 significance level, all methods control the type I error rate across the 10 pathways under different level of mean signalBack to article page
