Exercise 9.7 Example IX.17: In Gelman and Meng (1996, p. 193) it is argued that a uniform prior on the degrees of freedom (ν) essentially puts all of its mass on infinity. As an alternative, the authors suggest to take as prior p(ν) ∝ 1/ν2. Implement this suggestion into a WinBUGS program and evaluate the change in posterior estimates of the parameters. Do you agree with their statement?
