From: Empirical comparison of cross-platform normalization methods for gene expression data
Mean-mean plots for MAQC ILM and AFX data without cross-platform normalization. Scatter plots for each MAQC treatment group. Single platform plots were produced from random non-overlapping subsets of seven assays each selected from the MAQC data set for that platform and treatment group. Red lines are the line y = x, provided for visual comparison. Sub-titles indicated the r2 value for the plot.
