Dirichlet-Poisson-Binomial estimates with the tub prior. Probability estimates and inferences for S. cerevisiae log-phase data based on the DPB model with tub prior, α
= 1/l, for all genes. The 20 genes with the largest tag counts are arranged in decreasing rank order along the x-axis. The observed tag proportions are marked with open circles, the bias corrected MLE in open triangles. In this case analytically derived posterior modes deviate substantially from the corrected MLE while the estimated posterior mean is identical to it. Upper and lower marginal 95% Bayesian posterior bounds are also given.
