MAS5, RMA and GCRMA behaviour on inter-array correlation for samples of 3,4 and 5 arrays upon incremental noise addition by adding values from real arrays to values from permutated arrays before normalization. The "noise level" gives the fraction of the values that came from the permutated arrays (For more details see Materials and methods). The figure shows means and standard deviations, as in figure one using three different sample sizes, an even number, 4 (Figure 2B), and two odd numbers, 3 (Figure 2A) and 5 (Figure 2C).
