Occurrence rate estimates for the three regions R₁, R₂, and R₃, from the analysis of five, 25, and all 50 simulated datasets. The panels show the prior and posterior distributions (dotted and solid lines, respectively), and the true simulated values (vertical dashed lines). Each panel also shows the mean and standard deviation of the posterior distribution. The prior has a mean and a standard deviation of 0.5 and 0.28.
