From: Effect of various normalization methods on Applied Biosystems expression array system data
Reproducibility within sites: coefficients of variation are used to evaluate the impact of the 5 normalization methods on data reproducibility. (A) presents the CVs, of log2(signal), within site 1 for all 29,098 genes as a function of expression level measured by quantile normalization; (B) presents the CVs within site 1 for genes with TaqMan® assays as a function of TaqMan CT values. Lines represent lowess smoothing fitting curves of all data points from each normalization method.
