Figure 3From: Normalization of array-CGH data: influence of copy number imbalancesDifferences between Median and Lowess normalization. M-A plots of un-normalized log ratios with correction lines for Median (orange) and Lowess (green) normalization. The plots show data from figure 2 for data sets with mimicked fraction of; 5 percent (a), 15 percent (b), 25 percent (c), or 35 percent (d) of probes with gain.Back to article page
