Computed vs. true background (spike-in experiments). Experimental results (I 0P M) and theoretical predictions of the algorithms discussed here for a) probeset 37777_at (HGU95A, 1521a99 hpp_av06.CEL) and b) 209606_at (HGU133A,12_13_02_U133A_Mer_Latin_Square_Expt10_R1.CEL) spiked-in at concentration c = 0, i.e. absent from the hybridizing solution. All comparison were performed using freely available packages from the Bioconductor project.
