Table 4 Signal to Noise Ratio (SNR) for the two data sets.

From: Effects of mRNA amplification on gene expression ratios in cDNA experiments estimated by analysis of variance

Data set SNR without σ CGP SNR with σ CGP
Total set1 9.91 5.22
Conservative set2 5.38 5.30
  1. 1The total data set included 10579 genes detected on at least one of the twelve arrays. 2The conservative data set included genes found to have equal ratio expression between amplified and non-amplified material. σ CGP is the cell line specific GP effect and is the effect of primary interest.
