F-quantile plots of the NFM test statistics of non-spike-in genes. Quantile plots for the HGU95A, HGU133A, and Golden Spike datasets show that the theoretical F-distribution (vertical axis) is not a good approximation for the sampling distribution of the observed NFM test statistics (horizontal axis). A solid black curve represents the quantile plot for the test statistics of the non-spike-in genes in each full data and subset comparison. Deviations from the dashed red reference line of equality indicate departures from the theoretical distribution.
