Exercise 5.9 Show graphically that the data-translated likelihood principle is satisfied on the original scale of µ for a normal likelihood with σ given. Exercise 5.10 Show that Jeffreys rule for the negative binomial model gives θ−1(1 − θ )−1/2 and thereby violates the likelihood principle which states that inference should be based only on the observed data.
