Fig. 8. Comparison of intensity property profiles. Probe sets are comprised of N = 16 probe pairs, selected by the heuristic method (yellow dots), and N = 11 (blue triangles) and N = 16 (red squares) probe pairs, selected by the model-based method. Medians of probe set intensity property values are taken over 99 YTC probe sets for each target [T] concentration. Each probe set intensity property is the median of property (P) for the N selected probes. (A) P = Ln(IPM). (B) P = intensity discrimination, (IPM [minus] IMM) /(IPM + IMM).
