Robust Significance Analysis of Microarrays by Minimum β-Divergence Method

Figure 3

Performance evaluation using barplot of power estimated by different methods associated with varying proportions of DE gene. (a) In absence of outliers. (b) One outlier with each of 10% genes. (c) One outlier with each of 20% genes. (d) One outlier with each of 50% genes. Powers were estimated by eight methods (ANOVA, KW, SAM, LIMMA, EB, GAGA, BRIDGE, and proposed) based on top 200, 400, 600,800, and 1000 genes for small-sample case .
