Figure 2From: Comparison of Affymetrix data normalization methods using 6,926 experiments across five array generationsCorrelation values between randomly selected gene pairs. The correlations were calculated between 500 randomly selected genes through 6,926 samples. The four AGC-normalized datasets ZAGC, HKAGC, QAGC, and WBLAGC have mean values closer to zero than the others (ANOVA with multiple testing procedure, α < 0.01).Back to article page
