Figure 3From: A simple optimization can improve the performance of single feature polymorphism detection by Affymetrix expression arraysComparison of SFP detection performances using different statistical tests and background correlations. (a) Performances of the three statistical tests for called SFPs: classical Student's t-test (SAM, black and ANOVA, red) and a newly developed method for SFP detection (SNEP, blue). (b) The effects of six different signal corrections on SAM analysis: MAS5 (red), RMA (green), GCRMA (their affinity [magenta] and full model [yellow]), and global scaling (dark blue), and quantile normalization (light blue). Definition of "Sensitivity" and "FPR" is the same as in Figure 2.Back to article page
