Table 1 Number of differences detected: comparison of signal and ratio methods
From: Computational method for reducing variance with Affymetrix microarrays
Criterion for difference | Signal Method | Ratio Method |
|---|---|---|
t-test, P < 0.01 | 98 | 124 |
rank sum test, P < 0.01 | 85 | 107 |
SAM, false detection < 20% | 56 | 124 |
SAM, false detection < 5% | 0 | 20 |
