Figure A2

The effect of the shape parameter on the IG (left) and G (right) hyperprior. The black (solid), shows the hyperprior density p(θ) for β=3 and θ0= 1 × 10−12 (see Table 1). The blue (dashed) and red (dotted) curves correspond to the same expectation E(θ) with β=2 and β=4, respectively. The greater the weight of the tail is, the smaller the shape parameter is. This is shown by the colored interdecile range (IDR), i.e., the interval between 10 and 90% quantile, which is presented here with respect to E(θ). The colors correspond to those of the curves.
