Fig. 3.11. Histogram of the distribution of Fs permutation p -values resulting
from the contrast of iterPLIER-processed data for sample groups Mut_A versus
B6 (top left), Mut_A versus Vector (top right), and Vector versus B6 (bottom
center).
3.3.5. Average MA plot of normalized intensities
MA plots are used to visualize the similarity of groups of samples.
The x -axis represents the average log intensity of one factor level
versus another, whereas the y -axis represents the log ratio (Figs. 3.8
and 3.9).
