## Figure 6.
Boxplots of average absolute log (base 10) ratios between replicate arrays stratified
by presence proportion for different statistical methods.
(a) MBEI method; (b) AD method. The number of presence calls for a probe set in the 58 arrays for the
six boxplots are: 0–9, 10–19, 20–29, 30–39, 40–49, 50–58. The title of each boxplot
is the number of probe sets used for the boxplot. The average is taken over 29 replicate
pairs. Log ratios are not calculated for negative expression values or expression
values identified as 'array-outliers' by the MBEI method in either array of a replicate
pair, and are not used to calculate the average. 744 probe sets are not included as
their average absolute log ratios cannot be calculated for all the 29 pairs using
either method.
