The cumulative distribution function Pr(x) plotted as a function of frequency (x) for GO gene annotations contained within Human GOA. The straight line shows the region of the plots for which a power law was found to provide a good model of the data [25]. 1(a) Annotation from the biological process sub-ontology, 1(b) annotation from the molecular function sub-ontology, and 1 (c) annotation from the cellular component sub-ontology The measured power law exponents, β, (were 2.04, 1.83, and 1.73 respectively. For all graphs p-value > 0.55, suggesting that the power law does provide a plausible model of the data.
