Figure 4: Estimated Inverse Gamma (panel A) and Normal (panel B) prior
distributions for the cluster parameters α* and β*, respectively. The solid
lines indicate mean distributions, i.e. those obtained for the mean values
of the hyper-parameters a_{α} , s_{α} ,μ_{β} , . The dashed lines are distributions
obtained by adding or subtracting individually one standard deviation from
each relevant hyper-parameter. |
