Figure 1From: Intensity dependent estimation of noise in microarrays improves detection of differentially expressed genesNoise is intensity dependent: Typical scatter plot for two experimental repeats. Each dot represents a gene, (a) repeat1 vs. repeat2, the black line is the diagonal (repeat 1 = repeat 2), (b) difference vs. mean intensity. The black lines are the running average of the standard deviation estimator (dataset used: GSE19921).Back to article page
