Comparison of the observed frequency distribution to the inverse normal cumulative distribution, pooled data. Quantile-quantile plots show on y-axis the observed expression and on x-axis value of the corresponding inverse normal cumulative distribution. Microarray data are derived from HuGeneFL, using the cell line IMR90 with 11 samples, pooled data. A: expression range from -0.1 to 0.1, 62 probe sets; B: expression range from 500 to 1000, 185 probe sets; C: expression range from 500 to 1000, 185 probe sets, relative expression values (sample expression divided by the mean of 11 samples; data Novak et al. [10]).
