## Figure 2.
Boxplots of average pairwise correlations of s between two array sets. They are stratified by average lower presence proportion
in two array sets (the presence proportion of a probe set is the proportion of arrays
in an array set where the target gene is called 'present' by GeneChip's algorithm).
The average is taken over C(6, 2) = 15 pairwise comparison of two array sets for each
probe set, and the correlation is calculated using probes that are not identified
as an outlier in both array sets. The range of the average lower presence proportion
for the six boxplots are: (0, 0.17), (0.17, 0.34), (0.34, 0.51), (0.51, 0.68), (0.68,
0.85), (0.85, 1). The title of each boxplot is the number of probe sets classified
into this boxplot. Eleven probe sets with too few non-outlier probes to calculate
correlations for all 15 comparisons are not included in the boxplots. The average
lower presence proportion and average pairwise correlation for probe sets in Figure
1 are (a) 1, 0.95; (b), 0.93, 0.94; and (c) 0, 0.86.
