Prior sensitivity illustration. The figure shows the effect of varying the priors when calculating BMA scores for a single data set. In the upper panel, values 1/46, 1/460, 1/4600 (green, blue, red) were used for the structure prior parameter ξ with a fixed hyperparameter α equal to 3. In the lower panel, hyperparameter values 1, 3, 10 (green, blue, red) were used for α in the analysis with the structure prior parameter ξ fixed to 1/460.
