Following Exercise 13.15, compute the convergence diagnostic Rˆ 1/2 from (13.7.2) using varying sample sizes (e.g., 216, 217, ... ).

Repeat the demonstration chex131 with the improper prior parameters mentioned in Section 13.3: a1 = b1 = 0, a2 = b2 = 0, and φ0 large (say, 100 or more). This imbalanced problem does show some strange behavior.
