Figure 5: Histograms of the simulated marginal posterior distributions for the six pair correlations ri, i =
1, . . . , 6, when the pairwise priors are triangular distributed according to Example 3.3. The solid graphs
are the pairwise prior distributions and the dotted lines indicate the empirical correlations of (4.1).
