Results from bootstrap resampling of the posterior samples for the three regions R₁, R₂, R₃, and from the analysis of all 50 simulated datasets. Top: Posterior distributions for the fraction of stars with planets. Bottom: Posteriors for the average number of planets per star. The lines are the same as in Fig. 3. Note that the true values of f_R and λ_R are the same due to the way the simulated datasets were generated.
