Fig. (4) (A, B) Frequency histograms approximating the posterior distributions for linkages from Cdk7 to Nras (a statistically significant downregulation) and Cdk7 to Il1a (marginally significant downregulation). Histograms were derived by Bayesian analysis of the gene interaction network shown in Fig. (2C) using 70,000 out of 140,000 Markov-Chain Monte Carlo samples and prior distributions as shown in Table 4.
