Proportion of times each variable is selected by the models for approach 1, several values of P0, n0 and a0. The values of mean weights elicited by clinicians for each variable are equal to the length of the dashed lines. Each model is labeled with a different symbol. (a) P0 = P, n0 = n1; (b) P0 = 2P, n0 = n1; (c) P0 = P/2, n0 = n1; (d) P0 = P, n0 = 1.77 × n1; (e) P0 = 2P, n0 = 1.77 × n1; and (f) P0 = P/2, n0 = 1.77 × n1.
