Effects of probe number on the inferences of differential gene expression. The median number of gained (black) and lost (red) inferences of differential gene expression (Y-axes) in simulated data sets subjected to random probe masking relative to actual data are plotted against the number of probes in a probe set (X-axes) (see text for details). Error bars represent the observed range of inferred differential gene expression in the simulated data sets. Red and black data points are slightly off-set for visual clarity. Data from probe sets with even (Panels A, C, E, G, and I) and odd numbers of remaining probes (Panels B, D, F, H, and J) are presented separately, as described in Figure 3. The tissue from which the data was collected is indicated in the lower left hand corner of each panel. Note the different scales on the y-axes for heart and testes.
