Table 5 Results obtained for the leukaemia data. Table 5 reports the number of significant positive and negative genes (columns 2, 6), the cutoffs (columns 3, 7), the estimated FDR (FDR) and the estimated FDR with FP correction (FDR-c) from sam2.20 and the symmetric cutoff method (columns 4, 8). Column 5 reports the number of genes found significant by sam2.20 and the symmetric cutoff method from the list of informative genes [21].

From: A comprehensive evaluation of SAM, the SAM R-package and a simple modification to improve its performance
