Figure 5 .

Features of the expression profiles of the two types of lung cancer data.(a) Distribution of the log mean expression levels. The distribution of the outlier genes is shown distribution in blue. (b) Scatter plot of gene-specific means versus standard deviations. The red dots represent genes with low β-weights (p < 10−5); green dots represent genes with high weights (p < 10−5); and the blue dots represent the outlier genes. (c) When transcripts with little variation (standard deviation < 0.05) were excluded, the upper heavy tail observed in Figure 4 disappeared.
