Augmented Table 5. Links to Graphical Displays and Simulations
Each simulation seed links to a graphical display of simulation results.
 
(Seeds for simulations in Table 5 of the printed article are not available;
for each prior a second run is shown here with its known seed.)

Note: Table 5 shows Gibbs Estimates of prevalence from 10,000 simulated values after burn-in
(Data: 5 positive tests among 215 units of blood).
