Figure 5

Comparing the accuracy of different test statistics. Statistics were calculated for 3 replicate arrays from Dataset 4 and compared to the "gold standard" t-statistic for the remaining 20 arrays. The x-axis for all plots is the "gold standard" t-statistic. The y-axis shows: (a) average logged ratio Mavg, (b) standard t-statistic, (c) 90th percentile penalized t-statistic, (d) SAM penalized t-statistic, (e) Z-statistic using the Iavg pooling metric, or (f) Z-statistic using the Imin pooling metric.
