Distribution of log for the Arabidopsis thaliana data. The null distribution is depicted by the dashed line; it follows a normal distribution with zero mean and a standard deviation of 0.014. The solid line signifies the alternative distribution. The empirical distribution (indicated by the histogram) is composed of the null distribution (η0 = 0.8995) and of the alternative distribution (ηA = 0.1005).
