## Normalized Power Prior Bayesian Analysis

Posterior sampling in several commonly used distributions using
normalized power prior as described in
Duan, Ye and Smith (2006) <doi:10.1002/env.752> and
Ibrahim et.al. (2015) <doi:10.1002/sim.6728>.
Sampling of the power parameter is achieved via
either independence Metropolis-Hastings or random walk Metropolis-Hastings
based on transformation.
