Table 2 Means and standard deviations of posterior distributions from our two-parameter nonlinear model

From: How the wisdom of crowds, and of the crowd within, are affected by expertise

Experiment Crowd Parameter M SD BF10
1 Inner a 0.05 0.01 1417.13
   b 0.09 0.01 9.83 × 1014
  Outer a 0.10 0.02 9.78 × 1014
   b 0.045 0.005 1.69 × 1090
2 Inner a 0.005 0.004 0.02
   b 0.021 0.003 4.60 × 1016
  Outer a 0.024 0.004 7.28 × 1014
   b 0.003 0.001 5.14
  1. Corresponding Bayes factors are presented in the rightmost column
  2. These parameters correspond to the function a/t + b, in which a is estimated crowd variance (i.e., crowd wisdom) and b is estimated crowd bias. BF10 values ≥ 3 or ≤ .33 indicate convincing support for the alternative or null hypothesis, respectively
