Fig. 5From: Robust gene selection methods using weighting schemes for microarray data analysisEmpirical density of data points for scenarios 1, 2, 3, and 4. The solid line (a) for each plot is the density of control samples for target genes (a). The red dashed line (b) and green dotted line (c) are the densities of treatment samples for target genes. There are no green dotted lines (c) in the top-left and top-right plots because there are no outliers in scenarios 1 and 3Back to article page
