Figure 4From: Comparison of seven methods for producing Affymetrix expression scores based on False Discovery Rates in disease profiling dataTest statistics for ovary and colon data. For each of the seven processing methods, the number of probe sets exceeding a test statistic threshold t was calculated and plotted against log2 t. Results are shown for the colon data (left column), the ovary data (right column), and for the t-test statistic (top row), and the rank-sum statistic (bottom row).Back to article page
