Count data normalization. MA-plots of the count data corresponding to the YRI samples from Pickrell [12]et al. (2010) after applying the following normalization methods: (a) raw count data without any normalization; (b) normalization with the edgeR[2] package; and (c) normalization with the cqn[4] package. The x-axis (A) shows the average expression throughout female and male samples in log2 scale and the y-axis (M) shows the magnitude of the log2-fold change between female and male samples.
